ELECTRICAL COMPONENTS
The electrical components consist of the controller assembly, the batteries, and the motors. The batteries, motors, and
controller power module (if equipped) are located on the power base assembly. The controller is located on the seat
assembly. Connectivity between the controller and the motors, batteries, and the battery charger is provided by one or
more wiring harnesses. See figures 6 and 7.
!
Controller Connector: This is where the controller harness connects to the power base.
!
Ammeter: This displays the charger’s current output in amps.
!
Main Circuit Breaker: This 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 the power chair to “rest” for approximately one minute. Then, push in the circuit
breaker button, turn on the joystick/controller, and continue normal operation. If the main circuit breaker continues to
trip repeatedly, contact your Quantum Rehab Specialist.
!
Charger Power Cord Receptacle: This is where the battery charger cord plugs in when the batteries need to be
recharged.
!
Battery Connectors (Quick-Connectors): These provide a connection between the battery boxes and the electronics
tray.
!
Motor Connectors: These provide a connection between the motors and the electronics tray.
Anti-Tip Wheels
The power chair’s mid-wheel drive design provides superior performance and safety. The anti-tip wheels are an integral
part of this design because they provide you with stability during deceleration. See figure 5.
