ART
Alternate Ramp Time Selector. Separate acceleration and deceleration
ramps can be selected by connecting this terminal to +24. These ramps
are programmed by parameters 41, 44 and 45. See 21-MODE for more
information on when this function is active.
49, 52, 52
MOL
Motor Overload input terminal. Requires N.C. contact for operation, referenced to +24. Connected to +24 by a jumper wire at the factory.
10, 60, 72,
73
CTS
Coast to Stop. Connecting this terminal to +24 VDC turns the drive output
OFF, allowing the motor to coast to a stop. The inverter’s output is cut off,
not ramped to a stop. When the terminal is set to 0 V (open), the drive
output is reinstated and the output will ramp to the programmed frequency.
This function may be used when electro-mechanical brakes are required.
This feature can also be accessed in programming by the 41-RSEL
parameter to automatically coast to a stop on a stop command.
52, 72, 73
RST
External Fault Reset input terminal. After a fault, connecting this terminal
to +24 VDC will reset any fault.
ST1
ST2
ST3
Open collector NPN transistor output connections. Each output can be
individually programmed to respond to any one of eleven conditions (See
parameters 72-ST1, 73-ST2 and 74-ST3. Each output can sink up to 50
mA from a 24 VDC source.
6FS
This terminal provides a 24 VDC pulse train output which is 6 times or 48
times the output frequency of the inverter. Selected by parameter 88-FRO.
65, 73
COM
Control circuit common, electrical isolated from the AC line terminals.
66, 72
SIO+
Positive connection for the Serial Input/Output Operation communication
link. Responds to RS 485 protocol (see Section 5).
SIO-
Negative connection for the Serial Input/Output Operation communication
link. Responds to RS 485 protocol (see Section 5).
Normally open contact for the Auxiliary Relay. Will close when the relay is
activated. Rating is 115 VAC at 1 Amp.
72
59, 72, 73
59
Auxiliary Relay Common terminal. May release by appropriate adjustment
at one of eleven preset conditions (see parameter 75-STR).
Normally Closed contact for the Auxiliary Relay. Will open when the relay
is activated. Rating is 115 VAC at 1 Amp.

Environmental Considerations
The BERGES ACP 6000 Inverter is rated IP 54 (through 37 kW), indoor or outdoor use. This
is a sealed unit providing a degree of protection against falling rain, splashing water and
hose-directed water.
If your inverter will be subjected to high-pressure wash-down or atmospheric contaminants
such as acid or caustic vapours, or carbon, metallic, or corrosive dust, contact BERGES for
specific instructions.
In order to maintain the IP 54 (NEMA 4) integrity of the ACP inverter enclosure, some care
must be exercised when the cover is installed.
With the smaller chassis configurations (ACP 6000 thru 15 kW), the following cover
installation procedure shall be employed:
1. Snug each of the four (4) cover screws into place.
2. Sequentially tighten each screw until the gasket is compressed evenly. Tighten first one
corner then the opposing corner to minimize the chance of pinching the gasket.
