3-Pin Off-board Charger/Programming
Socket
You may use an off-board charger to charge your
power chair batteries through the 3-pin socket
located on the front of the VSI. See figure 8. If
you use an off-board charger, the charger current
should not exceed 8 amps. Contact your Pride/
Quantum Provider for more information.
WARNING! Only chargers with Neutrik NC3MX plugs should be connected to the off-board charger/
programming socket. See your Pride/Quantum Provider for more information.
NOTE: The socket may also be used for reprogramming the VSI. Contact a Pride/Quantum
Provider for more information.
3-Pin Onboard Charger (OBC) Connector
This connects the VSI to the onboard battery charger. This connection provides an inhibit that disables
the VSI when the onboard battery charger is on. The 3-pin OBC 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. It is typically mounted next to the controller connector
on the power base. Refer to your power chair owner's manual for exact location.
WARNING! Failure to properly align the connectors can result in damage to the VSI, the charger
harness, and the connectors.
9-Pin Controller Connector
This connects the VSI to the power chair's batteries, motors, and motor brakes. It is typically mounted
on the power base. Refer to your power chair owner's manual for exact location.
6-Pin Actuator Connector (For Optional Equipment)
This connects the VSI to optional equipment such as a lighting system or a power elevating seat. It is
typically mounted on the power base. Refer to your power chair owner's manual for exact location.
2-Pin Battery Connector
The 2-pin battery connector connects the controller to both batteries.
4-Pin Motor/Brake Connectors
The 4-pin motor/brake connectors connect each motor and brake to the controller. There are two motor/
brake connectors, one each for the left and right motors and brakes.
3-Pin Lighting Connector (For Optional Equipment)
The 3-pin lighting connector connects the VSI to a separate lighting module located on the power base.
