Main Circuit Breaker (located on the rear main frame): 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 con-
tinue normal operation. Turn on the controller, and continue normal operation. If the main circuit breaker contin-
ues to trip repeatedly, contact your Quantum Rehab Provider.
