About

This procedure provides instruction to remove and replace the ON/OFF Circuit Breaker.

Procedure

Review entire procedure before starting.

1. Set the treadmill circuit breaker to OFF and unplugDisconnect a device power cord plug or cable connector from the power receptacle or outlet. the treadmill’s power cord from the ACAlternating Current: electric current which periodically reverses direction between positive and negative polarity. outlet.
2. Remove the treadmill’s hood.
3. Remove the two screws that fasten the AC input panel to the frame. Keep fasteners for replacement installation.
4. Disconnect the wiring from the circuit breaker (2 blue wires on 120 Vac treadmills or 2 blue and 2 brown wires on 240 Vac treadmills) Note: The figure below is showing a 240 volt configuration.



5. Incline the AC input panel from the frame and rotate it to expose the AC input circuit breaker screws.



6. Remove the two screws and remove the circuit breaker. Keep fasteners for replacement installation.
7. Reference the label on the replacement circuit breaker and install the circuit breaker in its mounting position with the LINE side of the breaker facing the input module and the LOAD side of the circuit breaker facing the AC line filter. Install the circuit breaker using the previously removed fasteners.
8. Install wire connections as follows for the 120 VACvoltage in an alternating current circuit and 240 VAC models:

   1. 120 VAC: On 120 Vac treadmills connect the blue wire from the input module to the LINE terminal on the circuit breaker and the blue wire from the AC line filter to the LOAD terminal on the circuit breaker.

   2. 240 VAC: On 240 Vac treadmills connect the blue wire from the input module to the upper LINE terminal on the circuit breaker and the blue wire from the AC line filter to the upper LOAD terminal on the circuit breaker. Connect the brown wire from the input module to the lower LINE terminal on the circuit breaker and the brown wire from the AC line filter to the lower LOAD terminal on the circuit breaker.
9. Set the AC input panel in its mounting position and install using the previously removed fasteners.
10. PlugDevice power cord connector or electrical cable male connector that is inserted into an electrical receptacle "outlet" (also called the plug-in). in the power cord and Switch the input power ON.
11. Verify treadmill operation per " and return to service.
