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 not more than 40 A, 240 volts maximum CAUTION: 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. WARNING: Using an undersized generator or invertor with the ICM870 soft start can result in a dangerous condition. Always size your generator or inverter appropriately for your application. 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 4-minute anti-short cycle routine while providing diagnostic fault information by means of an LED indicator.

TYPICAL INSTALLATION NOTE: For Trane or American Standard units, T1 and T2 are labeled differently from Figure 1. Wire according to Figure 3 for those units. Step #1 Connect the (ICM870 RED WIRE) > to the run capacitor terminal (c/common/T2). See Figure 3 for Trane and American Standard (on these units the common will be T1). Step #2 a) Disconnect factory installed compressor run wire from the contactor terminal (T2). See Figure 3 for Trane and American Standard (removal of the compressor run wire on these units will be from T1 on the contactor). b) Splice the (ICM870 BROWN WIRE) > to the compressor run wire previously disconnected in (Step 2A) If there is a Start Capacitor and/or Start Relay already in place, disconnect them prior to installing the ICM870. Step #3 Connect the (ICM870 BLUE WIRE) > to the run capacitor terminal (herm/hermetic/start) Step #4 Connect or splice the (ICM870 BLACK WIRE) > to the contactor terminal (T1). See Figure 3 for Trane and American Standard ( on these models the ICM870 BLACK wire will connect to T2).

In those cases, wire as seen below. INSTALLATION Step #1 a) Disconnect factory installed compressor run wire from the common run capacitor / L2 terminal b) Splice the ICM870 BROWN WIRE > to the factory installed compressor run wire previously disconnected in step #1A. If there is a Start Capacitor and/or Start Relay already in place, additional steps will be required to disconnect them.
