Voltage Sensitivity Adjustment

The Back-UPS detects and reacts to line voltage distortions by transferring to battery backup power to protect connected equipment. In situations where either the Back-UPS or the connected equipment is too sensitive for the input voltage level it is necessary to adjust the transfer voltage setting.

1.Connect the Back-UPS to a wall outlet. The Back-UPS will be in Standby mode, no indicators will be illuminated.

2.Press and hold the ON/OFF button for 10 seconds. The ON/OFF button will illuminate alternately green-red, to indicate that the Back-UPS is in Program mode.

3.The Power On/Replace Battery LED will flash either green, or red to indicate the current sensitivity level. Refer to the table for an explanation of the transfer voltage sensitivity levels.

4.To select LOW sensitivity, press and hold the ON/OFF button until the LED flashes green.

5.To select MEDIUM sensitivity (factory default), press and hold the ON/OFF button until the LED flashes red.

6.To select HIGH sensitivity, press and hold the ON/OFF button until the LED flashes green and red simultaneously.

7.To exit Program mode wait five seconds and all LED indicators will extinguish. Program mode is no longer active.
