Off-board Charger/Programming Socket
You may use an off-board charger to charge the power chair batteries through the 3-pin socket located on the front of the
VSI. See figure 26. If you use an off-board charger, the charger current should not exceed 8 amps. Contact your Quantum
Rehab Specialist for more information.
WARNING! Only chargers with Neutrik NC3MX plugs should be connected to the off-board charger/
programming socket. See your Quantum Rehab Specialist for more information.
NOTE: The socket may also be used for reprogramming the VSI. Contact your Quantum Rehab Specialist for
more information.
NOTE: Changes to the programming can only be made by the manufacturer, an authorized representative of
the manufacturer, or a Quantum Rehab Specialist.
Controller Connector
This connects the VSI to the power chair’s batteries, motors, and motor brakes.
3-pin Charger Inhibit Connector
This connects the VSI to the onboard battery charger. This connection provides an inhibit that disables the VSI when the
battery charger is on. The charger inhibit connector is coded with colored dots. The dots are positioned so that you align
the flat side of the male connector with the flat side of the female connector before making the connection.
