The Output Voltage is user configurable and is designed to allow selecting or changing the desired output voltage to match the utility via the Liebert GXT2U Configuration Program provided with the UPS. The settings to choose from are 200, 208, 220, 230, and 240 VAC output. The factory default setting is 208 VAC.

! CAUTION

Never change the voltage settings while the UPS is ON and powering connected loads.

NOTE

Setting output voltage to 200 VAC will cause the UPS unit to be derated to 2400 VA, 1680 watts.
