4. Locate the feed through for the motor temp sensor and remove the connector.
Installation:
1. Install the sensor on the feed through.
2. Attach the connector to MOT RTD (J12) on the CCM Board.
3. Install the Service Side Cover.
4. Restore power to the Compressor.
With power applied to the Compressor, using a DC voltage meter, place the negative (-) test lead in the
TP1 - GND test point and verify the voltages at the test points listed in Table 25 (CCM Test Point Values).
