The Liebert PSI XR may be installed in either a tower or rack configuration. Determine the method 

that suits the application and proceed.
Decide where to install the Liebert PSI XR. The UPS must be installed indoors in a controlled envi-

ronment. Place it in an area with unrestricted airflow around the unit, away from water, flammable 

liquids, gases, corrosives and conductive contaminants (see Figure 6).
Maintain a minimum clearance of 12 inches (305mm) in the front and rear of the UPS. Maintain an 

ambient temperature range of 32°F to 104°F (0°C to 40°C).

The UPS and battery cabinets are heavy (see Table 6 and Table 7). Take proper precautions 

when lifting or moving either the UPS or battery cabinets.
