INSTALLATION

Preparation

1.Visually inspect the UPS for freight damage. Report damage to the carrier and your local dealer or Liebert representative.

! CAUTION

The UPS is heavy (see Specifications section). Take proper precautions when lifting or moving it.

2.Decide where to place the Liebert GXT2U. Install the UPS indoors in a con- trolled environment, where it cannot be accidentally turned off. Place it in an area of unrestricted airflow around the unit, away from water, flamma- ble liquids, gases, corrosives, and conductive contaminants. Maintain a minimum clearance of 4 inches (100mm) in the front and rear of the UPS. Maintain an ambient temperature range of 32°F to 104°F (0°C to 40°C).

NOTE

UPS operation in temperatures above 77°F (25°C) reduces battery life.

3.The Liebert GXT2U may be installed in either a tower configuration or in a rack, depending on available space and use considerations. Determine the type of installation and follow the appropriate instructions in either Tower UPS Installation or Rack-Mount UPS Conversion and Installation.

Tower UPS Installation

When using the Liebert GXT2U in a tower configuration, use the included support base (shown below, left) to stabilize the UPS.

If any battery cabinets are added, they will include spacers to accommodate the additional cabinets (shown below, right).
