There are two (2) variants of the CIM. Revisions A and B do not contain the connector numbers
(e.g., J5). The "Pin 1" indicators are also not present on the A and B revisions.
6. Route the cable out of the service side and CIM boxes.
Installation:
1. Route the new cable between the CCM and CIM.
2. Insert the 24 VDC connector to the CIM.
3. Insert the 24 VDC connector into J7 on the CCM Board.
4. Replace the covers.
5. Restore power to the Compressor.
After power is applied to the Compressor, ensure the light emitting diodes (LEDs) on the CIM are on
and communication is established.
The DC-DC-CCM 24V Cable passes 24 VDC from the DC-DC to the CCM.
