The Quantum/Jazzy 1450 Series Power Chair
Your power chair has two main assemblies: the seat
assembly and the power base assembly. Typically, the
seat assembly includes the armrests, seatback, and seat
base. The power base assembly includes two motor/brake
assemblies, two drive wheels, two caster wheels, two anti-tip
wheels, two batteries, and wiring harnesses. See Quantum/
Jazzy 1450 Series (page 4) and figure 1.
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 figure 1.
Controller Harness Connector: The controller harness
connector is where the controller plugs into the power base.
Each controller uses a different type of harness. Regardless of
which type of controller is used, the harness must be secured
to the seat assembly and not allowed to drag on the floor.
Motor Connectors: This is where the controller connects to
the motors.
Battery Connector: This is where the controller connects to
the batteries.
Controller Power Module: This enables the controller to
communicate with the batteries and the motors.
Main Circuit Breaker (located in front of the batteries
on top of the 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. The circuit
breaker will reset itself. Turn on the controller, and continue
normal operation. If the main circuit breaker continues to trip
repeatedly, contact your Quantum Rehab Provider.
