IMPORTANT SAFETY INFORMATION

HIGH VOLTAGE WARNING – Always turn off power at the main
service panel before installing.
CAUTION: The ICM870-32A must be mounted in an area where it will
not be exposed to water or the elements. Exposure of the ICM870-
32A soft start to water can cause failure of the control and is a risk for
fire or other electrical safety hazards.
Suitable for use on a circuit capable of delivering not more than 5,000
rms symmetrical Amperes, 240 V maximum when protected by a
circuit breaker having not more than 40 A, 240 volts maximum
Installation of any ICM870-32A soft start must be done by a certified
HVAC technician or licensed electrician. All installations are to be
done in accordance with local, state, and national electrical codes.

APPLICATION

The ICM870-32A is intended for Marine, Recreational Vehicle, HVAC
and commercial applications. The ICM870-32A integrates compressor
in-rush current over startup time, thus reducing peak current demand
on a power supply source (generator or other). The ICM870-32A
will monitor system health including voltage, current, compressor
startup and self integrity. Upon a fault condition, the ICM870-32A will
halt operation and initiate a 3 minute anti-short cycle routine while
providing diagnostic fault information by means of an LED indicator.
