Chapter 4 Troubleshooting
The 48 Vdc Extended Battery Cabinet is shipped with the battery
charged. However, it may lose some of its charge during shipping and
storage. You can use the XBU48 immediately after unpacking, but it
may not provide the full-rated backup time during a power failure. Upon
initial startup, the XBU48 may need to operate for approximately
24 hours to fully charge the battery and provide full battery-backup time.
Condition Possible Cause Action
System does not provide
the expected backup time. Battery circuit breakers are
in the OFF (O) position. Switch the battery circuit breaker to the ON (
|
) position
for all connected XBU48s.
