Operation in Battery Mode

SWITCHING FROM OUTPUT OFF TO UPS or UPS to BYPASS to OFF

1.If the UPS is in OUTPUT OFF condition, with all rear mounted breakers in the ON position, and the AC input LED and the bottom LED of the BATTERY/LOAD array lit. To go to UPS mode, press the UPS ON/ALARM /BATTERY TEST button until a “Beep” is heard. The UPS will then go through its start-up routine ending up after approximately 10 seconds with the UPS LED lit.

2.If the UPS is operating in UPS mode and there is a need to go to BYPASS mode, press the OUTPUT OFF/BYPASS button until a beep is heard. The UPS ON LED will extinguish and the BYPASS LED will be lit.

WARNING: In BYPASS mode your connected load is NOT PROTECTED from mains disturbances.

If you are in BYPASS mode and want to set the OUTPUT to OFF. Press the OUTPUT OFF/ BYPASS button for a least 1 second, twice, within a 4 second time interval. There is no audible “Beep” on this action.

If in the absence of the mains power it is essential for the UPS output to be made 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.
