Installing Battery Connection Panels - ABB Galaxy Power System Installation Manual

Installing Battery Connection Panels

Follow these guidelines for making connections during this procedure:
·
For all battery connection panels, connect the first wire lead toward the back of the cabinet.
·
On the panel with two bus bars, use the back four mounting locations on the top bus. On the
lower bus bar, use the front four locations.
Step
Before making any battery connections:
a. Verify that the battery fuses and alarm fuses are not installed.
b. If the panel is equipped with contactors, place the forced-off switches (SW100 and SW200) on the BJN board
in the forced OPEN position. See Figure 10-4.
Verify that all AC and DC protectors are OFF.
Terminate the appropriate conductors with terminal lugs as required. Use heat shrink insulating sleeves over any
Connect the cabinet end of the battery cables to the contactor, circuit breakers, or fuse holders and return bus.
Next connect the battery end of the cables. Tape the terminal lugs as required for safety during installation. If a
battery contactor, circuit breaker, or fuse is not being used to keep the batteries off the bus, do not connect the
leads at the batteries.
Use a DC voltmeter to check the voltages at the fuse holders, contactors, battery bus, and return bus. Verify the
polarity.
If the battery connection panel is equipped with contactors, do not place the forced-off switches (SW100 and
SW200) on the BJN board in the NORMAL position at this time. See Figure 10-4.
