ICM CONTROLS ICM870 Soft Starter Built-in Start Capacitor Installation Guide

9A / 16A

IMPORTANT SAFETY INFORMATION

HIGH VOLTAGE WARNING – Always turn off power at the main service panel before installing.

CAUTION: The ICM870 must be mounted in an area where it will not be exposed to water or the elements. Exposure of the ICM870 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 an interrupting rating not less than 40 rms symmetrical amperes, 240 volts maximum.

Installation of any ICM870 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.

ICM870 Comparable Amperage Crosses

The ICM870-9A and 16A models cross to the comparable amperage models from the following manufacturer’s

INSTALLATION

Step #1 a) Disconnect factory installed compressor run wire from the run capacitor (c/common/L2) terminal b) In its place, connect the ICM870 RED WIRE > to the run capacitor (c/common/L2) terminal

Step #2 Connect the ICM870 BROWN WIRE > to the factory installed compressor run wire previously disconnected in step #1a

If there is a Start Capacitor and or PTCR already in place, additional steps will be required to disconnect them.

Step #3 Connect the ICM870 BLUE WIRE > to the run capacitor (herm/ hermetic/start) terminal

Step #4 Splice the ICM870 BLACK WIRE > with the factory install compressor Overload Switch wire (OL/L1)

APPLICATION

The ICM870 is intended for Marine, Recreational Vehicle, and commercial applications. The ICM870 integrates compressor in-rush current over startup time, thus reducing peak current demand on a power supply source

(generator or other). The ICM870 will monitor system health including voltage, current, compressor startup and self integrity. Upon a fault condition, the ICM870 will halt operation and initiate a 3 minute anti-short cycle routine while providing diagnostic fault information by means of an

LED indicator.
