2000 ECS Battery Plant H569-416
4 - 12 Installation
Issue 2 August 1996
Step G - Load Wiring:
Open the dc distribution cover panel by turning the two 1/4 turn
fasteners located on the front of the panel and remove the circuit
breaker panel covers and discharge return cover.
Run paired leads (supply and return) to each load from a dc
distribution circuit breaker and from the discharge return bus.
The load supply leads are terminated at the battery plant end on
terminal blocks TB701 on the distribution printed wiring boards.
The load return leads are terminated at the battery plant end on
the discharge return bus, directly above the load supply lead
termination. The termination points for the load leads are
numbered 1 to 63, from left to right. Distribution breaker
positions are also numbered 1 to 63, from left to right.
Cable sizes of 2 through 8 AWG may be terminated in the
distribution with the use of a terminal adapter. This terminal
adapter requires the use of two termination positions.
To install a circuit breaker, first verify that the circuit breaker is
in the OFF position. Plug in the circuit breaker and visually
verify that the line, load, and alarm connections are properly
mated. (See Figure 2-7). Remove the knockout from the
associated position on the cover. Mark the new circuit on the
distribution cover label. Spare circuit breakers may or may not
be provided with the dc distribution panel, as ordered. Spare
circuit breakers may be stored in distribution panel if in the OFF
position. Leads may be run to spare circuit breaker positions in
anticipation of future growth (similarly to prewiring rectifier ac
input in Step D, above).
Recommendations for routing and dressing of load leads as they
leave the battery plant and enter the cable rack system are shown
on the plant assembly drawing, H569-416. Consult the job
application drawings for the routing of these leads to the load
equipment. A label is provided on the dc distribution cover that
may be marked to indicate each load breaker's use.
Before proceeding, verify that all load circuit breakers are in the
OFF position.
DANGER
Verify that no voltage is present on the dc distribution bus bars
and that all dc circuit breakers are off before connecting any
load leads.
