Product Usage Instructions
Important Safety Information
CAUTION: The ICM870 should not be mounted
against a residence or dwelling. It must be installed inside a
metal cabinet or a NEMA Type 3R Metal enclosure that houses the
compressor.
Installation of the ICM870 soft start should only be carried out
by a certified HVAC technician or licensed electrician in
compliance with local, state, and national electrical codes.
WARNING: When using the ICM870 with a
generator, ensure it is properly sized for the application to avoid
dangerous conditions.
Application
The ICM870 models have comparable amperage crosses with selected
manufacturers. Consult the manufacturer’s documentation for more
information.
Wiring Diagram for Installation
Refer to the provided wiring diagrams for general layout and
specific instructions on connecting the ICM870 soft start:
- Connect the ICM870 RED WIRE to contactor terminal T2.

IMPORTANT SAFETY INFORMATION
HIGH VOLTAGE DANGER Always turn off power at the main service panel before installing.
CAUTION: Never mount the ICM870 against a residence or dwelling. The ICM870 must be mounted inside the metal cabinet which houses the compressor or a NEMA Type 3R Metal enclosure.
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: If the ICM870 is to be used with a generator, consult a licensed electrician or qualified professional to properly size the generator for your application. Using an undersized generator or invertor with the ICM870 soft start can result in a dangerous condition.
Suitable for use on a circuit capable of delivering not more than 5,000 rms symmetrical Amperes, (Convient à des circuits produisant au plus 5,000 A eff. )240 V maximum when protected by a circuit breaker having not more than 40 A, 240 volts maximum
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 HVAC
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 contactor terminal 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 Splice the ICM870 BLACK WIRE > to the compressor Common and L1

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.
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 installed compressor Overload Switch wire (OL/L1)
