Transfer Voltage Adjustment (optional)

In situations where the Back-UPS or connected equipment appears too sensitive to input voltage, it may
be necessary to adjust the transfer voltage. This is a simple task requiring use of the front panel
pushbutton. To adjust the transfer voltage, proceed as follows:
1. Plug the Back-UPS into the utility power source. The Back-UPS will be in a Standby Mode (no

indicators lit).

2. Press the front panel pushbutton fully inward for 10 seconds. All indicators on the Back-UPS will

flash to acknowledge going into Programming Mode.

3. The Back-UPS will then indicate its current Lower Transfer Voltage, as shown in the following table.

4. To select 160 volts as the Lower Transfer Voltage, press the pushbutton until 1 indicator is flashing.

5. To select 180 volts as the Lower Transfer Voltage, press the pushbutton until 2 indicators are flashing.

6. To select 196 volts as the Lower Transfer Voltage, press the pushbutton until 3 indicators are flashing.

7. Once in Programming Mode, if the pushbutton is not pressed within 5 seconds, the Back-UPS will

exit the Programming Mode, and all indicators will extinguish.
