Lucent Technologies 415B Battery Plant for 4ESS
Issue 6 September 1999
Retrofit of 415A Battery Plant 7 - 27
6. Turn off the ac and reconnect the ac input lead.
7. Turn on the ac. The rectifier should restart. On the test box
only the PWR and MAN LEDs should light.
8. Repeat Steps 4 through 8 for the other two phases.
9. Reduce the load to zero.
10. Operate the Power switch to Off.
11. Disconnect and remove the Battery Plant Simulator Test
Set, the DMM (Digital Multimeter), and the dummy load.
Note: Repeat all tests for the second rectifier, if
equipped, from “Simulated Plant-Rectifier Interface
Tests Using Test Set (ITE 7102).”
12. Remove rectifier fuse head from 415A.
13. Reconnect the dummy load to the Control and Distribution
Bay charge and charge return bus bars.
Note: The dummy load does not have to be connected if
the 415A has a load greater than 160 amperes. The
plant load will be sufficient without it.
14. Replace rectifier fuse head in 415A.
Completion of
Test
1. Verify all REG fuses are removed from the Control and
Distribution Bay. Connect J202 and J208 on each rectifier.
2. Install the BAA5 converter packs (verify Galaxy
Controller is on line). Note: Ignore all alarms.
3. Install controller REG fuse.
4. Close the dc output circuit breaker of rectifier #1 following
the procedure outlined on the label above the breaker.
5. Turn off rectifier. (Use the Power ON/OFF switch at
rectifier.)
6. Install rectifier REG fuse.
