Installing Primary AC Power
Primary AC Power
For Installation of AC Power for CE / ATEX units, refer to the Application Drawing Package, and page 17
concerning the special requirements for these systems which will be different from the information
contained below. This section is documenting the requirements only for non-CE/ATEX units. The Maxum
II operates from 100-130 VAC or 187-264 VAC 47-63Hz, single phase.
WARNING Do not apply power to the unit until procedurally instructed to do so (this appears in a
later procedure in this manual.) Installation personnel shall adhere to all AC power (Mains)
specification requirements; see Application Drawing Package & Utility Diagram sheet. Failure to
do so, and operating the equipment in a manner not specified, can impair the safety protection
provided by the equipment.
Fuses
Fuses are located on the Power Entry Control Module located on the left sidewall of the Electronic
Enclosure. Fuse requirements are (see page 22 for part numbers and locations):
F1-ABH2: 16 Amperes, 115 VAC or 10 Amperes, 230 VAC
F2-ABH1: 16 Amperes, 115 VAC or 10 Amperes, 230 VAC
F3-FLT AC: 3.15 Amperes, 115 VAC or 230 VAC
F4-LWH: 10 Amperes,115 VAC or 230 VAC
F5-MWH: 6.3 Amperes,115 VAC or 230 VAC
WARNING No substitutes should be used for the fuses noted above. Most of these are sand
filled ceramic fuses with a very fast acting fuse to protect the heater relays. A fuse kit is available
which contains all of the listed fuses on page 42.
Power Consumption
Typical maximum power consumption for the analyzer is 1700 Watts (single oven heater) during warmup, and averages 500 to 700 Watts during operation. In addition, a sampling system with a heated
cabinet can consume from 30 to 2000 Watts, depending upon its particular arrangement. Refer to
Application Drawing Package, Block Diagram Utility Connections sheet for the analyzer’s specific voltage
and total power requirements (the wattage for the sampling system, if required, will also be given.)
Installation of Components
The following customer provided components are required for installation of primary AC power (if this is a
CE / ATEX installation, then the user should refer to the Application Drawing Package for specifics):
Primary AC Wire Size
Customer AC power wiring recommended is three wire 12 AWG for 115 VAC and 14 AWG for 230 VAC
with a hot, neutral, and ground.
