1. Confirm the CPR DC circuit breaker is off (down).
2. Place the batteries in the bottom of the cabinet with the negative terminals (-) at the rear of the
cabinet.
3. Connect the red battery lead from the lower shelf at the positive (+) terminal of the left battery.
Torque connection to 60 inch-pounds (6.8 Newton-meters).
4. Disconnect the red battery lead cable from the upper shelf at the positive (+) terminal of the left
battery. Reconnect this lead with the red lead of the inter-shelf connection cable.
5. Connect the two (2) battery interconnection jumpers as shown below. Torque all connections to
60 inch-pounds (6.8 Newton-meters).
6. Disconnect the black battery lead cable from the upper shelf at the negative (-) terminal of the
right battery. Reconnect this lead with the black lead of the inter-shelf connection cable. Torque
connection to 60 inch-pounds (6.8 Newton-meters).
7. Measure the DC voltage to ensure proper installation of all battery wiring. Open circuit DC voltage
should measure at least 36 volts across both parallel strings.
8. Verify the red and black Anderson connector pair is properly attached to the left side of the CPR
module.
