LCD Configuration and Status
Matching the Utility Voltage
Use configuration parameters to select the UPS voltage range (see Table 3-1).
•
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.
•
If the utility voltage frequently varies outside the operating range, update the UPS
configuration to match.
NOTE:
this chapter), you are setting the UPS output voltage.

To update the configuration:
1. Have a licensed electrician measure your utility voltage.
2. Use Table 3-1 to identify the operating range that most closely matches your nominal
utility voltage level.
3. Update the UPS output voltage as required. See the section, "Set Voltage," in this chapter
for more information.
