5.0 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 6.0 - Initial Start-Up and Electrical Checks.
Visually inspect the UPS for freight damage. Report any damage to the carrier and your local dealer
or Liebert representative.
Install the GXT2 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 (4 inches) in the front and rear of the UPS. Maintain an ambient temperature range of 0 to
40°C (32 -104°F).
5.1 Install the Main Cabinet
The GXT2 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 5.1.1 - Tower UPS Installation or 5.1.2 - Rack-Mount UPS Installation.
5.1.1 Tower UPS Installation
When using the GXT2 in a tower configuration, use the included support base (shown below, left) to
stabilize the UPS. If any external battery cabinets are added, they will include spacers to accommo-
date the additional cabinets (shown below, right).

5.1.2 Rack-Mount UPS Installation
When using the GXT2 in a rack-mount configuration, the UPS must be supported by a slide kit, fixed
rails or a shelf.
When using the optional Adjustable Rack Mount Kit, you will use the following instructions. The fig-
ures accompanying 5.1.3 - Installing the Adjustable Rack-Mount Kit—Sold Separately shows
the positioning of the rack-mounting brackets. Liebert recommends taking the internal batteries out
of the UPS during rack installation. This will make the UPS cabinet lighter and easier to handle.
!
CAUTION
The UPS is heavy (see 13.0 - Specifications). Take proper precautions
when lifting or moving it.
NOTE
UPS operation in sustained temperatures above 25°C (77°F) reduces battery life.
This device is intended for use in an Installation Category II environment.
!
CAUTION
Only three (3) M4 screws are used on the side of the GXT2 where the Power Distribution Box
is located. The fourth mounting hole is above the Power Distribution Box and is not used.
