5.2.1.2 Service Side
Assembly
1. Install the bearing sensor cables.
2. Apply a thin coating of dielectric grease to
the exterior of the bearing sensor feed through
connectors.
• • • CAUTION • • •
Do not apply any dielectric grease directly to bearing sensor feed through DB9 pins, only apply grease around bearing sensor
feed through connectors after the cables are connected to prevent moisture from entering the pin area.
3. Install the Motor-Cooling Valve Solenoid Coils.
4. Connect the solenoid actuator and bearing
sensor cables to the Backplane.
5. Reinstall all three modules: PWM, BMCC, and
Serial Driver, and connect the I/O Cable into the
Backplane Board.
6. Reconnect the PWM harness connectors to
the appropriate feed throughs (in the correct
orientation), then remove the connectors once
more. Wipe the excess dielectric grease from the
bearing feed through pins and reconnect the
PWM harness connectors to the appropriate feed
throughs in the correct orientation..
7. Reinstall Service Side Cover on compressor.
5.2.1.3 Top Side
1. Remove the top covers from the compressor.
2. Dry off any condensate around the motor
winding sensor terminals, high power feed
throughs and motor bus bars.
3. Using a soft-bristle brush, remove any debris
or dust from the motor winding sensor terminals,
high power feed through and motor bus bar
screws.
4. Spray greaseless lubricant on the terminals,
power feed throughs and bus bar screws to
remove any trace of moisture.
5. Wipe off excess lube with a lint-free rag.
6. Wait for surfaces to dry completely.
7. Once they are dry, apply a coat of rust inhibitor
spray on the terminals, power feed throughs and
bus bar screws.
8. Spray or apply dielectric grease on exposed
metal surfaces on the bus bar screws and motor
winding sensor terminals. (Figure 105 – Motor-
Winding Sensor Dielectric Grease Application)
