1.Remove the front bezel from the UPS.

2.UPS must be operating in Normal (AC) mode.

NOTE

Utility power will be applied to the connected load.

3.The AC Input, Load, and Battery Level Indicators should be lit.

4.Press the Voltage Programming button for at least 5 seconds to enter the Configuration mode. The UPS will beep and all of the indicators on the front panel display will flash on and off for about 5 seconds. The next cycle will display the current configuration, either 110, 120 or 127 VAC. One of the Load Level Indicators will be flashing. Initially, the 0%-25% Load Level Indicator will be flashing, indicating the default setting of 120V as shown in Figure 18.

5.Press the ON button to step through the voltage settings until the appropriate Load Level Indicator is flashing.

6.Press the Voltage Programming button. The UPS will return to Normal mode operation.

The Voltage Programming button allows the operator to select the utility transfer voltage at which the UPS will switch to battery power. This also changes the inverter voltages. The voltage settings are as follows:
