Installation
Reserve Power for Three or More Cabinets (Wall Mount)
1. Install the Battery Distribution Box (BBDB) to the bottom cabinet (see Figures 4-12 and 4-24).
The BCCB is not required for wall mount systems.
2. Connect two Cable “C” jumper wires from the positive terminal of one 12VDC battery to the
negative terminal of the second 12VDC batter, per Figure 4-18 (Cable “C” is supplied with the
BBTC1A-2.0M cable).
3. Ensure that a serviceable 15-amp fuse is installed in the in-line fuse holder of the BBTC1A-
2.0M battery cable.
4. Connect the white lead of the BBTC1A-2.0M battery cable to the open positive terminal of the
12VDC battery. Connect the black lead to the open negative terminal of the second 12VDC
battery.
5. Connect a second BBTC1A-2.0M in parallel to the first BBTC1A-2.0M cable per Steps 2, 3
and 4 instructions.
6. Plug the two BBTC1A-2.0M battery cables into the Battery Distribution Box.
Important! The cabinets must be connected to the (live) AC power source, and the power supply
On/Off switches set to On prior to the final step of connecting the reserve power
batteries to the power supplies via the BATT +/- receptacle. If the batteries are
connected after AC power is lost, reserve power will not function.
7. Connect the BBTC2A-2.0M cables from the Battery Distribution Box to the BATT +/-
receptacle of individual power supplies per Figure 4-12 (BBTC2A-2.0M cables are supplied
with an BBDB distribution box).
8. To test reserve power operation, disconnect the system AC power plugs with the power supply
On/Off switches in the On position. The system should continue to operate without
interruption.
Note If connecting four batteries, follow the wiring diagrams in Figure 4-18.
