Power cable installation
Description
This section provides instructions on installing the power cabling for the Alcatel-Lucent
1850 TSS-5 shelf.
Each power feeder (A and B) requires a single power feed from the battery distribution
fuse board (BDFB), or the battery distribution circuit breaker bay (BDCBB) to the
Alcatel-Lucent 1850 TSS-5 shelf.
If the Alcatel-Lucent 1850 TSS-5 is powered through only one power feed, the system will
report a minor alarm. To suppress the alarm, use two jumpers, one jumper between the -
VA and -VB and the second jumper between +VA and +VB. The gauge of both jumpers
should be the same as the gauge being brought in from either the Battery Plant (#12AWG
to #20AWG).
