remaining or battery
capacity is lower than
the battery low
warning level that is

actual time to
shutdown might vary
depending on the
UPS load and
presence of an
extended battery
module.
Shutdown Imminent
(Alarm #55)

The communication to
external devices stops
because the UPS has
entered a state where
it might abruptly stop
operating without

utility power returns.
The alarm is issued
when the battery time
remaining reaches
zero. All connected
devices should have
already shut down
gracefully.
