Lucent Technologies 1200A 24V ECS Battery Plant J85500E-2
Issue 7 October 1998
Installation 5 - 11
Load Wiring
1. 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.
2. 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 at the circuit breaker module block. 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 10 AWG may be terminated in the
distribution with the use of a terminal adapter. This terminal
adapter requires the use of two termination positions.
1. To install a circuit breaker, first verify that the circuit
breaker is in the OFF position.
2. Plug in the circuit breaker and visually verify that the line,
load, and alarm connections are properly mated. (See
Figure 2-7).
3. 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.
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, J85500E-2. 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.
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.
