Audible alarm
For critical situations a pattern of audible tones will be repeated every 5 seconds, according to the
table below. This audible alarm can be silenced by holding the ON/OFF switch on the front panel
in the “UP” position until a chirp is heard. A new alarm condition will cause the audible alarm to
be reactivated. Contact Factory for instructions on how to permanently silence the alarm.

Hot Swapping the Battery Packs
The battery packs can be removed from and reinserted into the UPS without disrupting the
delivery of power to the load as long as a source of input power is available. This feature is
referred to as “hot swapping” in the industry. It can be used to replace a battery pack that needs
servicing, or to replace a drained battery pack with a spare, fully charged one if additional back-
up protection must be ensured before the drained battery pack will have time to be recharged.
Of course, if there is no source of input power available and the UPS is therefore drawing power
from the batteries, then the removal of the battery packs would cause the UPS’s outputs to shut
down until a recharged battery packs are inserted. Both battery packs are required to deliver
power to the output. The UPS will not support the load on battery power with only one battery
pack installed.
