Lucent Technologies 415B Battery Plant for 4ESS
5 - 4 System Testing
Issue 6 September 1999
3. Verify that all alarm cables J202 are disconnected at the
208G boards inside all rectifiers. The other end is still
connected at the back of the Galaxy Controller.
4. Verify that all the remote sense cables J208 are still
connected at both the Galaxy Controller and at all 208G
boards in the rectifier.
5. Check that Battery Disconnect Switches (on Control and
Distribution Bay) are Off.
6. Make sure load boxes are turned off and at no load, then
connect the load boxes between the Charge and Discharge
Return buses.
7. Verify that the battery voltage and polarity at the top of the
Control and Distribution Bay is correct, i.e., “+” on the
switch bus bars and “-” on the Charge Return bus.
8. Operate battery disconnect switch(es) to the On position,
which connects power to the Control and Distribution Bay.
Result: the converters in the Control and Distribution Bay
should power up the Galaxy display, and, after a short
delay, the display will indicate battery voltage. The Galaxy
will also indicate any alarms that are present.
Note: Ignore alarms at this time.
9. At each ac cabinet, turn on the ac circuit breakers, then test
them by pushing the trip button to verify proper operation.
After testing, turn on the breaker by turning to full Off
position, then back to On.
10. Turn on the rectifier power switch of Rectifier #1. Adjust
rectifier output voltage to 151.9 volts.
11. Close the dc output circuit breaker of rectifier #1 following
the procedure outlined on the label above the breaker.
12. Turn off rectifier. (Use the Power ON/OFF switch at
rectifier.)
13. Install REG fuse.
14. Repeat Steps 10 through 15 for all rectifiers.
