* UPS goes to Overload Fault Status (Line Mode) when load levels of 125% or greater occur for a duration of 10
minutes and 20 seconds.
** UPS remains silent in Battery Backup Mode until low-battery notification occurs.
*** UPS goes to Overload Shutdown (Battery Mode) with load levels of 110% or greater; Shutdown occurs
within 36 seconds.
Alarm Configuration Note: The alarm is factory configured to remain silent in battery mode until the low-
battery threshold occurs.
To configure the alarm to sound immediately in response to a power failure, press and hold the POWER
BUTTON until a single beep is heard, then release. The alarm will now be configured to sound immediately
when a power failure occurs.
IMPORTANT! The Power Button must be released immediately after the first beep in order to change the
alarm off/on status. Holding the switch down until the second beep will immediately power off the UPS.
Alarm OFF/ON status can be changed as the UPS runs in AC or Battery mode. Changing alarm status
activates a UPS preset that automatically remains in place until the next reset.
