Lucent Technologies ECS Minicell Battery Plant H569-420
5 - 8 Installation
Issue 5 February 1997
Load Wiring
Open the dc distribution cover panel by turning the two 1/4 turn
fasteners located on the front of the panel.
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
the distribution panel. 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 42, from left to right. Distribution
breaker positions are also numbered 1 to 42, from left to right.
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 2-4). Remove the plastic knockout from the
associated position on the front cover. Mark the new circuit on
the distribution front 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 the 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 E, above).
Before proceeding, verify that all load circuit breakers are in the
OFF position.
Initial Charge
Batteries may undergo initial charging at this time, according to
the manufacturer's recommendations. One of the rectifiers may
be used for initial charging. Refer to the procedures given in the
Battery and Rectifier manuals.
Controller Test
Follow the controller test procedure given in the ECS controller
manual to complete the steps below.
1. Test Enable/disable equalize charge feature.
DANGER
Battery voltage is present behind the distribution cover.
Remove all jewelry before working in this area. Use insulated
tools only.
