Electrical Components
The electrical components are located on the power base. The main circuit breaker is located on the front of the battery tray. The controller connector and the motor connectors are located on the power module, inside the power base. See figure 7.
Main Circuit Breaker: The main circuit breaker is a safety feature built into your power chair. When the batteries and the motors are heavily strained (e.g., from excessive loads), the main circuit breaker trips to prevent damage to the motors and the electronics. If the circuit trips, allow your power chair to “rest” for approximately one minute. Next, push in the circuit breaker button, turn on the controller, and continue normal operation. If the main circuit breaker continues to trip repeatedly, contact your Quantum Rehab Provider.
