Electrical System

The electrical system is powered by two long-lasting, 12-volt, deep-cycle batteries. These batteries are connected in series to
provide 24 volts of direct current (DC). The main electrical components consist of the batteries, a battery charging system, the
main circuit breaker, the motor/brake assembly, and the controller (see figures 1, 2, 4, and 9). Refer to "Pilot Controller" or
"Dynamic DL-50 Controller" for more specific information on the controller.

ELECTRICAL COMPONENTS AND CONNECTIONS

The controller is connected to the battery and the motors through two electrical connections: the controller connector and the
charger harness connector. Both are located on the electronics tray at the back of the power chair. See figure 4.
CONTROLLER CONNECTOR
CHARGER HARNESS CONNECTOR
Figure 4. Electronics Tray
Controller Connector: This is where the controller is connected to the batteries and motors.
Charger Harness Connector (for onboard charger only): This is where the charger connects to the controller. It provides
an inhibit which prevents the controller from functioning during charging.
Ammeter: The ammeter displays the charger's current output in amps.
Onboard Charger AC Power Lead Receptacle: This is for your battery charger power lead. The lead is typically located in
the seat pocket.

MAIN CIRCUIT BREAKER

The main circuit breaker is a safety feature built into your Jet 7. It is located on the back battery box. See figure 4. When the
batteries and the motors are heavily strained (e.g., from excessive loads), the main circuit breaker will trip to prevent damage
to the motors and the electronics. If the circuit breaker trips, allow the Jet 7 to "rest" for approximately one minute. Then, push
in the circuit breaker button, turn on the controller power, and continue normal operation. If the main circuit breaker trips
repeatedly, contact your authorised Pride provider.

CHARGING YOUR BATTERIES

The batteries are sealed and maintenance free, so there is no need to check the electrolyte fluid level. Deep-cycle batteries
are designed to handle a longer and deeper discharge. Though they are similar in appearance to automotive batteries, they
are not interchangeable.
CAUTION! Automotive batteries are not designed to handle a long, deep discharge, and are unsafe for use in
power chairs.
