Install Reserve Power for One or Two Cabinets

1.Connect the black jumper wire (supplied with the PBTC1A-3M cable) from the positive terminal of one 12VDC battery to the negative terminal of the second 12VDC battery (Figure 5-4).

2.Ensure that a serviceable 10-amp fuse is installed in the in-line fuse holder of the PBTC1A-3M cable.

3.Connect the PBTC1A-3M battery cable white lead to the open positive terminal of the 12VDC battery. Connect the black lead to the open negative terminal of the second 12VDC battery.

Important! The cabinet(s) must be connected to the (live) AC power source, and the power supply On/Off switch set to On prior to the final step of connecting the reserve power batteries to the power supply via the BATT+/- receptacle. If the batteries are connected after AC power is lost, reserve power will not function.
