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: When you set the voltage through the LCD panel (as described in the “Setting the Voltage”
section of this chapter), you are setting the UPS output voltage

200 166-240 200
208 166-248 208
220 176-264 220
230 (default) 184-276 230
240 192-288 240
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. Refer to the section, “Setting the Voltage,” in
this chapter for more information.
