Disassemble the Encoder - Later Version
1. Block the motor shaft (3) to prevent rotation.
For example, use a wrench to hold the motor shaft in place.
2. Remove the mounting screws from the encoder connector (10).
3. Remove the rear cover, or fan cover if provided, from the motor.
4. Remove the wire ties that secure the encoder cable and thermostat wires to the motor
frame.
5. Remove any electrical tape covering the thermostat connectors (9), and then disconnect
the thermostat leads from the thermostat connector.
6. Remove the screws (8) and washers (7) from the spring mounting plate (4).
7. Loosen the shaft clamp screw (6).
8. Remove the motor encoder (1).
9. Remove the plastic shaft sleeve (2) from the motor shaft, if it was not removed with the
encoder.
ATTENTION: Verify that power is off or removed from all devices affected by the encoder.
Verify that all electrical connections (for example, items 9 and 10 in the HPK-Series Motor Encoder
- Later Version ) are disconnected from any power source.
BURN HAZARD: Outer surfaces of the motor can reach high temperatures, 125 °C (275 °F), during
operation.
Take precautions to prevent accidental contact with hot surfaces on the motor. Consider the surface
temperature of the equipment when selecting cables and additional equipment for connection.
Failure to observe these safety procedures could result in personal injury or damage to equipment.
