Lucent Technologies 415B Battery Plant for 4ESS
7 - 2 Retrofit of 415A Battery Plant
Issue 6 September 1999
Configuration 3 uses the H569-429 Group 4 frame, which is
equipped with a six-rectifier alarm panel, battery disconnect/
reconnect switches, a Galaxy Controller, seventeen 100-ampere
distribution breakers with precharge and 100 ampere/25mV
shunts, 140/48-volt converter, and a Remote Peripheral Monitor
Panel with three 221F modules for reading the currents from the
main distribution panel. The Group 5 is the same except the
distribution has 60-ampere circuit breakers.
Restrictions
Retrofit of the 415A system using Configuration 1 or 2 to
parallel the 415B system has two qualifying factors:
1. The 415A rectifier must be manufactured by “ASCOM
WARREN”. This is the only rectifier that has been verified
by the design requirements.
2. When adding the second rectifier, the failed unit must be in
the same module. If this is not the case, the entire 415A
should be replaced with the 415B Group 4 with the
five-rectifier application.
Configuration 1
(Adding One
Rectifier)
Configuration 1 is the installation of one Control and
Distribution Bay (H569-429) with one rectifier. The rectifier is
directly connected to the Control and Distribution Bay.
Requires:
(1) H569-429 Group 3 with no distribution
(1) J87132B-2 ferroresonant rectifier
(2) Bus bars (supplied) for replacement of fuse in
415A distribution
(1) H569-429 Group 24 (wireset for 2 red and red
with trace and 2 blue and blue with trace for
connecting the rectifier)
Configuration 2
(Adding Two
Rectifiers)
Configuration 2 is the installation of one Control and
Distribution Bay with two rectifiers. Both rectifiers are directly
connected to the Control and Distribution Bay; the Control and
Distribution Bay is directly connected to the 415A distribution.
Requires:
(1) H569-429 Group 3 with no distribution
(2) J87132B-2 ferroresonant rectifiers
(2) Bus bars (supplied) for replacement of fuse in
415A distribution
