Matching the Utility Voltage
Configuration parameters are used to select the UPS voltage range.
■If the utility voltage is within this range, the UPS supplies utility power to the output receptacles.
■If the utility voltage is outside this range, the UPS supplies battery power to the output receptacles. Maximize your battery life by configuring the UPS so that the utility voltage is normally within the selected voltage range.
If the utility voltage frequently varies outside the operating range, update the
UPS configuration to match.
1.Select the appropriate nominal utility voltage (200, 208, 220, 230, 240 VAC, and “auto sensing,” a default of 208/230V.
2.Select the appropriate utility voltage range from the table below:

To update the configuration:
3.Have a licensed electrician measure your utility voltage.
4.Use the table above to identify the operating range that most closely matches your utility voltage.
5.Update the nominal utility voltage level and/or utility voltage range parameters as required. See the section, “Set Voltage,” in this chapter.
