available for a critical operation, then the following procedure should be followed.
1. To start the UPS in BATTERY mode, press the UPS ON/ALARM /BATTERY
TEST button for at least one half second until you hear the audible alarm
gives a double “Beep” to signal acceptance of the command. After a short
delay, the BATTERY LED should light. The UPS will then initiate a self-test
and approximately 10 seconds after these tests are completed, the UPS ON
LED will light. Connected load equipment may now be started.
PLEASE NOTE- duration of output power will be limited to remaining battery
capacity shown by the battery LED’s.
2. To power down the UPS. Press the OUTPUT OFF/ BYPASS button until the
audible alarm “Beeps”. The UPS will now shutdown and all LED’s extinguish.
