Nominal Input Voltage

If the utility power consistently fluctuates outside of the configured

UPS voltage range, the UPS repeatedly corrects the input voltage by

switching to battery power.

You can configure the UPS to more closely match the nominal input

voltage by selecting a different input voltage or extending the input

voltage range. The default is auto-sensing to 208/230V.

1. Have a qualified electrician measure the utility voltage.

2. Use the System Setup Menu to access the Set Voltage parameter

(see page 42).

3. Select one of the following options: 200V, 208V, 220V, 230V,

240V, 208/230V auto-sensing, or 230V extended. Use the

following table to help select the appropriate voltage.

200V Nominal +20%/–17% 166-240V

208V Nominal ±20% 166-248V

220V Nominal ±20% 176-264V

230V Nominal ±20% 184-276V 166-288V

240V Nominal ±20% 192-288V

4. Update the nominal input voltage range and/or the extended

utility voltage range parameters as required.
