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.

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.
