Lucent Technologies 415B Battery Plant for 4ESS
Issue 6 September 1999
Retrofit of 415A Battery Plant 7 - 51
•
Remove all load.
•
Reconnect the control (J202) and REG (J208) cables to the
208G board of each rectifier. Reinstall the REG fuses.
•
Turn on all rectifiers and wait 10-20 seconds.
•
Operate the battery disconnect switch to On for each
position that has a battery string connected to it.
Rectifier Equalize
Adjustment (on
Battery)
1. Set the plant load to zero.
2. Turn off all rectifiers via their POWER switches.
3. Remove control cable J202 ONLY from each rectifier at
the 208G board.
4. On the 208G circuit pack of each rectifier, operate DIP
switch S205.3 to Off. This will enable local equalize in
each rectifier.
5. Turn one rectifier On via the POWER switch.
6. Set the plant load to 10 - 20 amperes.
7. Operate the Float/Equalize switch on the front of the
rectifier to EQUALIZE. Adjust the rectifier output voltage
to 156 volts.
8. Operate the Float/Equalize switch to Float.
9. Turn the rectifier off via the POWER switch.
10. Disable local equalize by operating DIP switch S205.3 to
On.
11. Repeat Steps 5 through 10 for all rectifiers.
12. Remove load. Reconnect control cables J202 to each
rectifier at 208G board.
Upon completion of this procedure, turn all rectifiers On with
the POWER switch.
