Maximum load must not exceed that shown on the UPS rating label. The UPS is designed for data processing equipment. If uncertain, consult your local dealer or Liebert representative. This UPS is designed for use on a properly grounded (earthed), 50Hz or 60Hz, 120V supply (programmable for 100, 110, 115, 120 and 127VAC output). - Page 6 Turn the UPS off and isolate the UPS before cleaning; use only a soft cloth, never liquid or aerosol cleaners. Keep the front and rear vents free of dust accumulation that could restrict airflow. When replacing batteries, replace with the same Liebert authorized replacement battery kits.

• The amount of distortion reflected on the utility is reduced. This results in cleaner power being available to other devices in the building not being protected by the Liebert GXT2U. NVERTER In normal operation, the inverter utilizes the DC output of the power factor correction circuit and inverts it into precise, regulated sinewave AC power. -
