5 INSTALLATION AND CONFIGURATION
Do NOT attempt to start the UPS, turn on any circuit breaker or energize the input power until instructed to do so in Initial
Startup and Electrical Checks on page 41.
Visually inspect the UPS for shipping damage. Report any damage to the carrier and your local dealer or Emerson
representative.
CAUTION: The UPS is heavy (see Specification). Take proper precautions when lifting or moving it.
Install the Liebert GXT3 indoors in a controlled environment, where it cannot be accidentally turned off. Place it where air
flows unrestricted around the unit. The installation location must be free of water, flammable liquids, gases, corrosives and
conductive contaminants. Maintain a minimum clearance of 100mm (4inches) in the front and rear of the UPS. Maintain an
ambient temperature range of 0 to 40°C (32 -104°F).
NOTE: UPS operation in sustained temperatures outside the range of 15-25°C (59°-77°F) reduces battery life.
5.1 Install the Main Cabinet
The Liebert GXT3 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 on
page 23 or Rack-Mount UPS Installation on page 25.
