11 - 8 Battery Connection Panels Issue 12 August 2012
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.
Installing Battery Connection Panels
Step Action
1 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 11-5 or
11-6.
2 Verify that all ac and dc protectors are OFF.
3 Terminate the appropriate conductors with terminal lugs as
required. Use heat shrink insulating sleeves over any
exposed lug shanks as necessary.
4 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.
5 Use a dc voltmeter to check the voltages at the fuse holders,
contactors, battery bus, and return bus. Verify the polarity.
6 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 11-5 or 11-6.
