3.3 Preparation for Installation
3.3.1 Installation Environment
Unpack the UPS and conduct the following checks:
• Install the UPS indoors in a controlled environment, where it cannot be accidentally turned off.
The installation environment should meet the specifications listed in Specifications.
• Confirm UPS installation area is an area of unrestricted air-flow around the unit, away from
water, flammable liquids, gases, corrosives, and conductive contaminants. Avoid direct sunlight.
• The utility power outlet should be nearby and easily accessible.
• This UPS is not for use in an Information Technology Equipment (ITE) room as defined in the
standard for the Fire Protection of Information Technology Equipment ANSl/NFPA 75.
NOTE: Operating the UPS in temperatures above 25° C reduces battery life.
3.3.2 Installation Clearances
Maintain at least 100 mm clearance in the front and rear. Do not obstruct the air inlets on the front panel
and rear panel. Blocking the air inlets reduces ventilation and heat dissipation, shortening the service life
of the UPS.
3.4 Installing the UPS
3.4.1 Installation Environment
The 2U and 3U UPS and optional battery cabinets (not supported on LI models) may be installed in a
tower or rack configuration. Determine the configuration that meets your application needs, see Tower
