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 (4 inches) in the front and rear of the UPS. Maintain an ambient temperature 

range of 0 to 40°C (32 -104°F).

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 5.1.1 - Tower UPS Installation or 5.1.2 - Rack-Mount UPS Installation.

To install the Liebert GXT3 as a tower:
1. Take out support bases from the accessories bag (see Figure 6).

2. If optional Liebert external battery cabinets will be connected to the Liebert GXT3, take out the 

spacers shipped with the battery cabinet.

3. Connect the spacers and the support bases as shown in Figure 6. Each Liebert GXT3 needs two 

assembled support bases, one in the front and one in the rear.

4. Adjust the direction of the operation and display panel and logo on the Liebert GXT3.

a. Remove the front plastic bezel cover as shown in Figure 7.

The UPS is heavy (see 12.0 - Specifications). Take proper precautions when lifting 

or moving it.

NOTE
UPS operation in sustained temperatures outside the range of 15-25°C (59°-77°F)
