Section 1 - Safety
IMPORTANT SAFETY INSTRUCTIONS - This
manual contains important instructions that should be
followed during installation and maintenance of the
generator and batteries. SAVE THESE INSTRUCTIONS.
Before operating the generator set (genset), read the
Operator’s Manual and become familiar with it and
the equipment. Safe and efficient operation can be
achieved only if the equipment is properly operated
and maintained. Many accidents are caused by
failure to follow fundamental rules and precautions.
The following symbols, found throughout this manual,
alert you to potentially dangerous conditions to the
operator, service personnel, or the equipment.
1.1 Advisory and Cautionary Statements
Advisory and Cautionary Statements are used
throughout this manual to call attention to special
information, correct operating procedures, and safety
precautions.
NOTE: A general advisory statement relating to
equipment operation and maintenance procedures.
IMPORTANT: A specific advisory statement intended
to prevent damage to the equipment or associated
components.
Cautionary Statements consist of three levels:
DANGER
This symbol warns of immediate hazards which
will result in severe personal injury or death.
WARNING
This symbol refers to a hazard or unsafe practice
which can result in severe personal injury or
death.
CAUTION
This symbol refers to a hazard or unsafe practice
which can result in personal injury or product or
property damage.
CAUTION
Fuel And Fumes Are Flammable.
Fire, explosion, and personal injury or death can
result from improper practices.
• DO NOT fill fuel tanks while the engine is running unless the tanks are outside the engine
compartment. Fuel contact with the hot engine
or exhaust is a potential fire hazard.
• DO NOT permit any flame, cigarette, pilot light,
spark, arcing equipment, or other ignition source
near the generator set or fuel tank.
• Fuel lines must be adequately secured and free
of leaks. The fuel connection at the engine
should be made with an approved flexible line.
Do not use copper piping on flexible lines as
copper will become brittle if continuously
vibrated or repeatedly bent.
• Natural gas is lighter than air, and will tend to
gather under hoods. Propane is heavier than air,
and will tend to gather in sumps or low areas.
NFPA code requires all persons handling propane to be trained and qualified.
• Be sure all fuel supplies have a positive shut-off
valve.
• Be sure the battery area has been well-ventilated prior to servicing near it. Lead-acid batteries emit a highly explosive hydrogen gas that
can be ignited by arcing, sparking, smoking, etc.

WARNING
Exhaust Gases Are Deadly.The engine exhaust
from this product contains chemicals known to
the State of California and some of its constituents cause cancer, birth defects, or other reproductive harm.
• Provide an adequate exhaust system to properly
expel discharged gases away from enclosed or
sheltered areas and areas where individuals are
likely to congregate. Visually and audibly inspect
the exhaust daily for leaks per the maintenance
schedule. Make sure that exhaust manifolds are
secured and not warped. Do not use exhaust
gases to heat a compartment.

Section 2 - Introduction
2.1 About This Manual
2.3 Application and Installation
This manual provides installation instructions for the
generator set models listed on the front cover. This
includes the following information:
A power generation system must be carefully
planned and correctly installed for proper operation.
This involves two essential elements: application and
installation.
Mounting Recommendations - for fastening
the generator set to the base and space requirements for normal operation and service.
Mechanical and Electrical Connections - covers most aspects of the generator set installation. Pre-start - checklist of items or procedures
needed to prepare generator set for operation.
Initial Startup - tests the complete system to
ensure proper installation, satisfactory performance, and safe operation. Refer to Operator
Manual for troubleshooting information.
Installation Checklist - reference checks upon
completion of installation.
This manual DOES NOT provide application information for selecting a generator set or designing the
complete installation. If it is necessary to design the
various integrated systems (fuel, exhaust, cooling,
etc.), additional information is required. Review standard installation practices. For engineering data specific to the generator set, refer to the Specification
and Data Sheets. For application information, refer to
Cummins Application Manual T-030, Liquid Cooled
Generator Sets.
2.2 Installation Overview
These installation recommendations apply to typical
installations with standard model generator sets.
Whenever possible, these recommendations also
cover factory designed options or modifications. However, because of the many variables in any installation, it is not possible to provide specific
recommendations for every situation. If there are any
questions not answered by this manual, contact your
nearest Cummins distributor for assistance.
Application (as it applies to generator set installations) refers to the design of the complete power generation system that usually includes power
distribution equipment, transfer switches, ventilation
equipment, mounting pads, and cooling, exhaust, and
fuel systems. Each component must be correctly
designed so the complete system will function as
intended. Application and design is an engineering
function generally done by specifying engineers or
other trained specialists. Specifying engineers or
other trained specialists are responsible for the
design of the complete standby system and for
selecting the materials and products required.
Installation refers to the actual set-up and assembly
of the power generation system. The installers set up
and connect the various components of the system
as specified in the system design plan. The complexity of the system normally requires the special skills of
qualified electricians, plumbers, sheet metal workers,
etc. to complete the various segments of the installation. This is necessary so all components are assembled using standard methods and practices.
2.4 Safety Considerations
The generator set has been carefully designed to
provide safe and efficient service when properly
installed, maintained, and operated. However, the
overall safety and reliability of the complete system is
dependent on many factors outside the control of the
generator set manufacturer. To avoid possible safety
hazards, make all mechanical and electrical connections to the generator set exactly as specified in this
manual. All systems external to the generator (fuel,
exhaust, electrical, etc.) must comply with all applicable codes. Make certain all required inspections and
tests have been completed and all code requirements
have been satisfied before certifying the installation is
complete and ready for service.
Natural Gas Generator Set Installation Manual-GF Series
Doc. 17855, Rel. 03/2014

2.5 Standby Heating Devices
2.6 Product Modifications
In accordance with NFPA 110, Cummins NPower recommends installing generator sets (life safety systems) equipped with engine jacket water coolant
heaters in locations where the minimum ambient temperature is below 4°C (40°F). NFPA also requires that
the engine jacket water coolant be maintained at a
minimum of 32°C (90°F) and, for most applications,
accept the emergency load in 10 seconds or less.
Agency certified products purchased from Cummins
NPower comply only with those specific requirements
and as noted on company product specification
sheets. Subsequent modifications must meet commonly accepted engineering practices and/or local,
state and national codes and standards. Product
modifications must be submitted to the local authority
having jurisdiction for approval.
The Engine Cold (Code 1435) message, in conjunction with illumination of the warning light is provided to
meet the requirements of NFPA 110. The engine cold
sensing logic initiates a warning when the engine
jacket water coolant temperature falls below 21°C
(70°F). In applications where the ambient temperature falls below 4°C (40°F), a cold engine may be
indicated even though the coolant heaters are connected. Under these conditions, although the generator set may start, it may not be able to accept load
within 10 seconds. When this condition occurs, check
the coolant heaters for proper operation. If the
coolant heaters are operating properly, other precautions may be necessary to warm the engine before
applying a load.
The information, specifications, and recommended
guidelines in this manual are based on information in
effect at the time of printing. Cummnis Npower, LLC.
and Cummins, Inc. reserves the right to make
changes at any time without obligation. If you find differences between your engine and the information in
this manual, contact your local Cummins Authorized

Section 3 - Installation
3.1 Mounting the Generator Set
Generator set installations must be engineered so the
generator set will function properly under the
expected load conditions. Use these instructions as a
general guide only. Follow the instructions of the consulting engineer when locating or installing any components. The complete installation must comply with
all local and state building codes, fire ordinances, and
other applicable regulations. Consider these requirements before installation:
•
Level mounting surface
•
Adequate cooling air
•
Adequate fresh induction air
•
Discharge of generator set air
•
Non-combustible mounting surface
•
Discharge of exhaust gases
•
Electrical connections
•
Accessibility for operation and servicing
•
Noise levels
•
Vibration isolation
3.1.1 Location
Generator set location is decided mainly by related
systems such as ventilation, wiring, fuel, and
exhaust. The set should be located as near as possible to the main power service entrance. Exhaust must
not be able to enter or accumulate around inhabited
areas.
Provide a location away from extreme ambient temperatures and protect the generator set from adverse
weather conditions. An optional housing is available
for outside operation.
WARNING
Incorrect installation, service, or parts replacement, can result in severe personal injury, death,
and/or equipment damage. Service personnel
must be trained and experienced to perform electrical and mechanical component installation.
IMPORTANT: Depending on location and intended
use, federal, state, or local laws and regulation may
require the customer to obtain an air quality emissions permit before beginning installation of the
genset. Be sure to consult local pollution control or air
quality authorities before completing construction
plans.
3.1.2 Mounting
Generator sets are mounted on a steel skid that provides proper support. The engine-generator assembly is isolated from the skid frame by rubber mounts
that provide adequate vibration isolation for normal
installations. Where required by building codes or
special isolation needs, generator sets may be
mounted on rubber pads or mechanical spring isolators. The use of unapproved isolators may result in
harmful resonances and may void the genset warranty.
Mount the generator set on a substantial and level
base such as a concrete pad. A non-combustible
material must be used for the pad.
Use 16 mm or (5/8) inch anchored mounting bolts to
secure the generator set skid to the floor to prevent
movement.
3.1.3 Access To Set
Generally, at least 1 meter (3 ft) of clearance should
be provided on all sides of the generator set for maintenance and service access. (Increase clearance by
width of door if optional housing is used.) A raised
foundation or slab of 150 mm (6 in) or more above
floor level will make servicing easier.
Lighting should be adequate for operation, maintenance and service operations and should be connected on the load side of the transfer switch so that
it is available at all times.
Natural Gas Generator Set Installation Manual-GF Series
Doc. 17855, Rel. 03/2014
3-1
3.1.4 Mechanical Connections
The generator set mechanical system installation
includes connecting the fuel, exhaust, ventilation and
cooling systems. Before starting any type of fuel
installation, all pertinent state and local codes must
be complied with and the installation must be
inspected before the unit is put in service.
IMPORTANT: All pipe threaded fuel system fittings,
including container fittings, must be assembled using
a pipe joint sealing compound designed for use with
natural gas or propane as applicable per industry
standards.
3.1.5 Base Drains (Optional)
Some units are equipped with drain extensions that
allow for oil or coolant (or both) drains to be brought
out to the base edge for convenient maintenance.
These drains have an in-line ball valve or Fumoto
valve installed for control. Factory drains require no
further installation at site.
3.2 Fuel System
These gensets can be equipped to operate on:
Support fuel lines to restrain movement and prevent
chaffing or contact with sharp edges, electrical wiring
and hot exhaust parts.
CAUTION
Sparks and hot surfaces can ignite fuel, leading
to severe personal injury or death. Do not route
fuel lines near electrical wiring or hot exhaust
parts.
Fuel lines must be routed and secured per local, state
and national codes.
Install a dry-type fuel filter ahead of the service pressure regulator to protect the sensitive pressure regulating components and orifices downstream from rust,
scale and other solid substances carried along in the
gas stream.
3.2.2 Natural Gas/Propane Vapor/Propane Liquid
Fuel System (Dual Fuel System)
• Natural gas
• Combination of natural gas and propane (Dual
Fuel for select models)
In all fuel system installations, cleanliness is of the
upmost importance. Make every effort to prevent
entrance of moisture, dirt or contaminants of any
kind. Clean all fuel system components before installing
3.2.1 Fuel Lines - Routing
A flexible fuel hose(s) or section of flexible fuel
hose(s) must be used between the engine’s fuel
system and fuel supply line to protect the fuel system
from damage caused by vibration, expansion and
contraction. Genset fuel supply line must be dedicated supply line from utility.
CAUTION
Fuel leaks create fire and explosion hazards
which can result in severe personal injury or
death. Always use flexible tubing between engine
and fuel supply to avoid line failure and leaks due
to vibration. The fuel system must meet applicable codes.
3-2
Installation of the fuel hose must be done according
to all applicable codes and standards, and installation
recommendations provided by the manufacturer. The
flexible hose used must be approved by the hose
manufacture for use with the genset fuel type and
product application.
WARNING
Gaseous fuels are flammable and explosive and
can cause severe personal injury or death. Do not
smoke if you smell gas or are near fuel tanks or
fuel-burning equipment or are in an area sharing
ventilation with such equipment. Keep flames,
sparks, pilot lights, electrical arcs and arc-producing equipment and all other sources of ignition well away from genset and areas sharing
ventilation. Keep a type ABC fire extinguisher
handy.
WARNING
NFPA No. 58 requires all persons handling and
operating propane to be trained in proper handling and operating procedures.
Gaseous-fuel supply system design, materials, components, fabrication, assembly, installation, testing,
inspection, operation and maintenance must comply
with the applicable codes. See NFPA No. 37, No. 54,
and No. 58.
Most codes require both manual and electric (batterypowered) shutoff valves ahead of the flexible fuel
hose(s). The manual valve should be of the indicating
Natural Gas Generator Set Installation Manual-GF Series
Doc. 17855, Rel. 03/2014
type. The electric valve should be wired so that the
valve is closed when the genset is off.
The recommendations in Cummins Application
Manual T-030 should be followed in regard to fuel
supply system pipe sizes, manual shut-off valves, fuel
filters, and gas pressure regulators.
3.2.3 Fuel Supply Pressure
WARNING
High gas supply pressure can cause gas leaks
which can lead to fire and severe personal injury
or death. Gas supply pressure must be adjusted
to Specifications by qualified personnel.
For propane (vapor withdrawal) and natural gas, the
maximum permissible fuel supply pressure is 5.0 kPa
(20 in WC) and the recommended minimum is 3.7
kPa (15 in WC).
For propane (liquid withdrawal), the maximum permissible fuel supply pressure is 2,153 kPa (312 psi)
under any operating condition.
WARNING
Gaseous fuel leaks into an inadequately ventilated space can lead to explosive accumulations
of gas. Natural gas rises when released into the
air and can accumulate under overhanging hoods
and inside housings and buildings. Propane
sinks when released into the air and can accumulate inside housings, basements and other belowgrade spaces. Precautions must be taken to
prevent gas leaks and the accumulation of
gaseous fuel in the event of a leak.
3.2.6 Regulator (Optional)
Prime regulators are available on some models for
fuel pressure reduction from source. Regulators vary
by manufacturer and model. Check with your distributor or service technician for details on use and settings of your Regulator. Factory Regulator requires
no further installation at site, connect fuel supply.
3.2.7 Fuel Filters (Optional-MOH models only)
Our in-line fuel filters are designed for optimal performance of the generator set. They provide the best
choice for Customers who want to extend service
intervals and increase Genset uptime. Optional pressure indicators and automatic drains are available on
some models. Check the installation and service
manuals for your specific filter (models vary by unit)
for details. Factory Fuel Filter require no further
installation at site, connect fuel supply.
3.3 Battery Selection
The minimum recommended reserve capacity (SAE
RC) and cold cranking ampere (SAE CCA) values for
a particular engine can be found on the Model specific Genset specification sheet is provided with the
genset (visit www.cumminsnpower.com for genset

in SAE Standard J537. All battery information is for
lead/acid batteries.
3.3.1 Battery Requirements
For battery replacement information, refer to Figure
3-1. Batteries may be supplied by Cummins Distribution as an option, or may be supplied by the customer.
3.2.4 Check Gas Leaks and Correct
All fuel-system connections, including the container
with associated valves and fittings, must be tested for
leaks with a soap and water solution or equivalent,
while the system is under pressure.
3.2.5 Fuel Heater (Optional-MOH models only)
PECO fuel heaters are available on some MOH
models. They are designed to provide heating of
engine fuel for optimal performance of the Genset.
The PECO Fuel Heater is designed to provide uninterrupted fuel flow in cold temperature environments
when it is needed most. Factory Fuel Heater requires

WARNING
Inhalation of exhaust gases can result in severe
personal injury or death. Do not use exhaust heat
to warm a room, compartment or storage area.
Pipe exhaust gases to the outside of any enclosure.
Locate the exhaust outlets away from any air inlets to
avoid gases re-entering the enclosure. Exhaust
installations are subject to various detrimental conditions such as extreme heat, infrequent operation and
light loads. Regularly inspect the exhaust system
both visually and audibly to see that the entire system
remains fume tight and safe for operation.
WARNING
Inhalation of exhaust gasses can result in severe
personal injury or death. Use extreme care during
installation to provide a tight exhaust system.
Terminate exhaust pipe away from enclosed or
sheltered areas, windows, doors and vents.
For indoor installation, the exhaust system shall use
sealed joint type fittings, (for example NPT fittings) to
provide a tighter exhaust system. Use of slip type fittings (secured with a muffler clamp) may allow
leakage of exhaust gases into the building.
The exhaust system design should meet Federal,
State and local code requirements.
Use an approved thimble (Figure 3-2) where exhaust
pipes pass through walls or partitions. Insulated wall/
roof thimbles are used where exhaust pipes pass
through a combustible roof or wall. This includes
structures, such as wood framing or insulated steel
decking, etc. Uninsulated wall/roof thimbles are used
where exhaust pipes pass through a non-combustible
wall or roof, such as concrete. Refer to NFPA 37

WARNING
Hot exhaust pipes can start a fire and cause
severe injury or death if improperly routed
through walls. Use an approved thimble where
exhaust pipes pass through walls or partitions.
Rain caps are available for the discharge end of vertical exhaust pipes. The rain cap clamps onto the end
of the pipe and opens due to exhaust discharge force
from the generator set. When the generator set is
stopped, the rain cap automatically closes, protecting
the exhaust system from rain, snow, etc.
Use a section of flexible exhaust pipe between the
engine and remainder of exhaust system. Support
exhaust system to prevent weight from being applied
to engine exhaust outlet.
Shield or insulate exhaust lines if there is danger of
personal contact. Allow at least 305 mm (12 in) of
clearance if the pipes pass close to a combustible
wall or partition. Before installing insulation on
exhaust system components, check the exhaust
system for leaks while operating the genset under full
load and correct all leaks.
WARNING
Exhaust pipes are very hot and they can cause
severe personal injury or death from direct
contact or from fire hazard. Shield or insulate
exhaust pipes if there is danger of personal
contact or when routed through walls or near
other combustible materials.
3.5 Installation of Sensors
On select model specific engines the natural gas, O2
and temp sensors to be mounted in exhaust ports
located pre and post catalyst. See Figure 3-4 and
Figure 3-5. Customer is responsible for installation of

3.6 Air Fuel Ratio (AFR) Controller
Select model specific natural gas engines are
equipped with an air fuel ratio controller, and are
designed to meet emission requirements for EPA, SI,
and NSPS codes. The engines are also capable of
meeting NSPS emissions standards with an AFR
controller and factory supplied catalyst.
The AFR control system uses a O2 sensor architecture with catalyst, if applicable, to control exhaust
emissions. The AFR control system controls fuel flow
based on exhaust O2. The controller opens or closes
the fuel control valve (FCV) in the fuel line based on
feedback from the O2 sensor(s).
3.7 Catalyst-Removable Elements (Only
available on some models)
Some Gensets require a 3-way or Oxidation catalyst
to meet emission requirements. There is a precious
metals element inside the housing of the catalyst that
converts exhaust to EPA requirements. Some catalysts have a removable body that can be replaced
with a new element when required. Most catalysts
come installed on Genset from factory. Some catalysts require customer mounting. Check with your distributor or service technician for details on your
product.

specifications as required by the engine manufacturer.
11. The catalyst must be installed to guarantee air
exhaust temperature into the catalyst of 482°649° C (900°-1200° F). Any temperature outside
this range may affect catalyst performance or
life.
2. The owner is responsible for periodic inspection
of the system in accordance with these and
other operational instructions.
3. The owner is responsible for maintaining the
operation of the engine in a way that would NOT
adversely affect the natural gas 3-way catalyst
system. Any misfire, stack detonations, oil or
debris in the exhaust system, shall be recorded
in the equipment’s service record.
4. The owner is responsible for maintaining complete oil consumption and service records, as

3.9 Air Fuel Setting and Emission Measurement
This procedure shall be performed at the time of
installation of the natural gas 3-way catalyst, after any
re-assembly, and periodically per schedule provided
by manufacturer throughout the life of the 3-way catalyst.
Follow the air fuel ratio controller’s instructions and
engine manufacturer’s instructions to set the air fuel
ratio. Analyze the engine exhaust gases with a Nox,
CO, or HC analyzer down stream of the 3-way catalyst.
If the emissions do not meet specifications, replace
the catalyst module(s) as needed.
3.10 Ventilation and Cooling
Generator sets dissipate heat and fumes that must be
removed by proper cooling and ventilation.
Generator sets in factory-mounted housings for
outdoor installation are designed for proper cooling
and ventilation.
Indoor installations require careful design with
respect to cooling and ventilation. In an indoor installation, all radiator cooling air must be discharged outdoors. Duct adapter kits are available. See Figure 3-6
for a typical indoor installation.
WARNING
Engine or radiator cooling air may carry deadly
carbon monoxide gas which can cause asphyxiation and death. All engine or radiator cooling air
must be discharged outdoors. Do not use it for
heating a room or compartment.
3.11 Vents and Ducts
For indoor installations, locate vents so incoming air
passes through the immediate area of the installation
before exhausting. Install the air outlet higher than
the air inlet to allow for convection air movement.
Size the vents and ducts so they are large enough to
allow the required flow rate of air. The ”free area” of
ducts must be as large as the exposed area of the
radiator. Refer to the genset data sheet for the airflow
requirements and allowed airflow restriction.
3-10
3.12 Oil Reservoir (Optional)
5 or 10 gallon Oil Tanks are optional on some units to
allow for extended service intervals between maintenance. These tanks are typically plumbed to an Oil
Maintainer Switch that controls the flow into the
engine oil pan. It is imperative the switch is functioning properly without obstruction and if the switch is
vented, the vent is not obstructed as well. The tank
should be filled with oil per Engine Manufacturer
guidelines.
3.13 Dampers
Dampers or louvres protect the generator set and
equipment room from the outside environment. Their
operation of opening and closing should be controlled
by operation of the generator set.
In cooler climates movable or discharge dampers are
used. These dampers allow the air to be recirculated
back to the equipment room. This enables the equipment room to be heated while the generator set
engine is still cold, increasing the engine efficiency.
3.14 Radiator Set Cooling Requirements
Radiator set cooling air is drawn past the control end
of the set by a pusher fan that blows air through the
radiator (Figure 3-6). Locate the air inlet to the rear of
the set. Make the inlet vent opening 1-1/2 times
larger than the radiator area.
NOTE: Louvers and screens over air inlet and outlet
openings restrict air flow and vary widely in performance. A louver assembly with narrow vanes, for
example, tends to be more restrictive than one with
wide vanes. The effective open area specified by the
louver or screen manufacturer should be used.
Locate the cooling air outlet directly in front of the
radiator and as close as possible. The outlet opening
must be at least as large as the radiator area. Length
and shape of the air outlet duct should offer minimum
restriction to airflow.
Attach a canvas or sheet metal duct to the air outlet
opening using screws and nuts so duct can be
removed for maintenance purposes. The duct prevents recirculation of heated air. Before installing the
duct, remove the radiator core guard.
Natural Gas Generator Set Installation Manual-GF Series
Doc. 17855, Rel. 03/2014
3.15 Remote Radiator Cooling Requirements (Available on All Models)
Remote radiator plumbing will vary with installation.
Follow recommendations given in Cummins Application Manual T-030. See product Data Sheet provided
with the genset (visit www.cumminsnpower.com for
genset specifications) for friction head and static
head limits.
The remote radiator cooling system substitutes a
remote mounted radiator and an electrically driven
fan in place of mounted components. Removal of the
radiator and the fan from the set reduces noise levels
without forcing dependence on a continuous cooling
water supply (necessary with heat exchanger cooling). The remote radiator installation must be completely protected against freezing.
1

3
IMPORTANT: Before filling cooling system, check all
hardware for security. This includes hose clamps,
capscrews, fittings and connections. Use flexible
coolant lines with heat exchanger or remote mounted
radiator options.

Some generator sets are capable of producing a wide
range of voltages and connection configurations,
others have specific limited capabilities. Refer to
wiring diagram and generator voltages (from the
nameplate) when reviewing the voltage connection
information and use the wiring diagram supplied with
your generator set when actually performing load
connections.
CAUTION
Reconfiguring generator sets to higher voltages
can exceed the voltage capability of the specific
generator windings. This will damage the generator, decrease line current, and render line circuit
breakers too large. Consult with your distributor
before performing reconnection for a different
voltage.
All loads are connected to the generator by bolting
stranded load wires to the appropriate terminals on
the generator reconnection terminal block or circuit
breaker lugs. The terminals are stamped U, V, W and
N to indicate the line and neutral connections. (Reference: U, V, and W correspond with L1, L2 and L3;
and N with L0 respectively).
4.6.3 Load Balancing
When connecting loads to the generator set, balance
the loads so the current flow from each line terminal
(L1, L2 and L3) is about the same. This is especially
important if both single phase and three phase loads
are connected. Any combination of single phase and
three phase loading can be used as long as each line
current is about the same, within 10 percent of
median value and no line current exceeds the nameplate rating of the generator. Check the current flow
from each line after connections by observing the
control panel display.
4.6.4 Current Transformers
The CT’s must be installed as noted in the following
CT Installation Requirements.
Refer to the reconnection diagram to identify the
output leads/phase that must be routed through each
CT, and also appropriate transformer post selection
for meter sensing leads. The transformers are labeled
CT1, CT2 and CT3 on the reconnection wiring diagram. (The reconnection diagram is located on the
upper side cover of the control housing.)
CT Installation Requirements:
The CT has a dot on one side. This dot must be
facing toward the generator (conventional current
flowing into the dot). A dot is also used to indicate pin
1 of the CT.
a. CT1 - U load leads (A phase)
CAUTION
Reconfiguring generator sets to lower voltages
can reduce generator set ratings, and also
increase line current, rendering line circuit breakers too small. Consult with your distributor before
performing reconnection for a different voltage.
4.6.2 Load Connections
Flexible conduit and stranded conductors must be
used for connections to take up movement of the
generator set.
b. CT2 - V load leads (B phase)
c. CT3 - W load leads (C phase)
d. Route the appropriate load wires through
each CT. The CT’s have dual secondaries (3
posts). The CT secondary wire marked 1 is
connected to post 1 of the CT. CT secondary
wire marked 2/3 is connected to post 2 for
high voltage gensets or to post 3 for low
voltage gensets. (Refer to the Reconnection

5.6 Emissions Requirements
WARNING
It is the owner/operator’s responsibility to complete site specific emission requirements to
ensure compliance with the US EPA SI NSPS.
Emissions on this Generator Set must be dialed-in at
the job-site per the following requirements before
operation:
GTA855E refer to manual 4325956 and AEB 10.124
and 24.52
KTA19SLB and QSK19 refer to AEB 28.07
the ignition system are functioning properly.
Especially check air cleaner restriction due to dirt
accumulation.
IMPORTANT: Read the warranty statement provided
with the genset for US Environmental Protection
Agency (EPA) restrictions on servicing specific components.
5.7.1 Fuel Supply Pressure
The fuel supply pressure must be 3.75-5 kPa (15-20
inches WC) under full-load operation not to exceed
5.0 kPa (20 inches WC) under any condition. See
Figure 5-1 for the pressure test ports.
5.7 Fuel Pressure and Mixture Adjustments
WARNING
Gaseous fuels are flammable and explosive and
can cause severe personal injury or death. Do not
allow cigarettes, flame, pilot lights, arcing
switches or equipment in area or areas sharing
ventilation. Keep a type ABC fire extinguisher
nearby.
WARNING
Natural gas is lighter than air, and will tend to
gather under hoods. LPG is heavier than air, and
will tend to gather in sumps or low areas. NFPA
Standard No. 58 requires all persons handling
and operating LPG to be trained in proper handling and operating procedures.

5.7.2 Fuel System Components
Engine is equipped with one shut-off solenoid valve
and a demand pressure regulator. Gensets for
optional liquid withdrawal of propane are equipped
with a converter that vaporizes the fuel with hot
engine coolant. See Figure 5-2 for a typical fuel
system. A genset equipped for dual fuel, natural gas
and propane, has a gas mixer that serves both fuels.
A fuel pressure switch to detect loss of natural gas
pressure is provided for automatic changeover to
propane while the engine is running. Manual shut-off
valves are provided in each supply line for manual
changeover systems.
5.7.3 Fuel System Operation
During normal operation, the engine fuel/air ratio is
determined by the fuel trim valve operating in conjunction with the oxygen sensor and the air/fuel
control module. Your authorized Cummins distributor
can monitor fuel system/oxygen sensor operation
using the service tool.

5.7.4 Fuel Mixture Adjustments
IMPORTANT: Always use Nox and CO test equipment to set emission levels.
1. Check for recommended fuel supply pressure
3.7-5.0 kpa (15-20 inches WC) at engine
mounted regulator
2. Check the operation of fuel shut-off solenoids.
5.7.4.1 Electronic Engines
For electronic engines:
• Model GTA855E see Cummins AEB 24.51.
• Model KTA19 SLB and QSK19, see Cummins AEB
28.07. Model 150 GFPA, GFMC, and GCDC are self
adjusting per engine manufacturer. Visit
www.psiengines.com for additional information and
updates.
5.7.4.2 Non-Electronic Engines
Some engines are site compliant capable. Generator
set certification is per local, regional and national
codes and may require frequent site testing. A
summary of the testing procedure is listed here. For
non-electric engines, apply 100% load.
1. Install the emission tester in the exhaust post
catalyst. The emission tester needs to read Nox
and CO in grams per break horsepower (g/bhp).
Install an O2 meter per catalyst in port on turbo
exhaust elbow.
2. Connect the laptop to RS232 connection at the
Gill air-fuel ratio controller module. Start the
engine. Click on the Gill icon when connected,
click on View, then click on Fuel Valve Control.
(The engine has to be running for the laptop to
connect to the air-fuel ratio controller.)
3. On the screen, go to the Mode column, and click
on Open Loop. The air-fuel valve will go to the
closed position.
4. Apply full generator name plate load.
5. All adjustments and emission readings need to
be at full load of the generator rating.
6. Run at full load for 5 minutes. Check O2 at the
turbo exhaust elbow. It should be at 0.5. If O2 is
not at 0.5, proceed to step 7. If at 0.5, proceed to
5-4
step 10. THIS READING NEEDS TO BE WITH
AFR IN OPEN LOOP.
7. Adjust the carburetor air-fuel mixing screw. If O2
is above 0.5, turn screw out. This will lower the
O2 setting. If O2 is below 0.5, adjust the carburetor screw in, this will raise the O2.
8. Run the engine for 5 minutes and check the O2
setting. Repeat adjustment until O2 is at 0.5.
9. Under the Mode column, click on Close Loop,
and the fuel valve will open.
10. Run the engine for 5 minutes. Check the
exhaust emissions. Emission should be under 4
g/hp for CO and under 2 g/hp for Nox. O2
reading, post catalyst should be 0.0 to -0.3.
11. O2 reading at the turbo exhaust elbow should
drop to about 0.1.
12. If the emission readings are not correct, the airfuel ratio controller will need to be adjusted.
13. Under the Control column, record the number in
the set point box. (This is in case you need to go
back and start from the beginning).
14. Double click on the set point box. It will turn red.
Now you can change the set point value.
15. Change the set point value in small increments
(sample if the set point is -0.1550, change to 0.1750), click Enter on the laptop. This will save
the new set point and the box will change back
to white.
16. Wait 5 to 10 minutes after every adjustment
before taking the emission readings. Be very
patient doing this part of the set up. Making a
change to the setting before emissions have stabilized will make it very difficult to get AFR
adjusted correctly.
17. As the set point value goes up, the valve will
open more.
18. Under output, you will see % Open and Steps.
This is the amount the valve is open. The
maximum opening is 200 steps.
19. The CO and NOx reading will fluctuate.
