5. Installation
Before installing the UPS, select a proper location to install the UPS.
• Place the UPS on a flat and clean surface, away from vibration, dust, humidity, high temperature, flammable liquids and
gases and corrosive and conductive contaminants. Install the UPS indoors in a clean environment, away from windows
and doors.
• Use the UPS at a maximum altitude of 3281 ft. (1000 m) to keep UPS normal operation at full load. In high-altitude areas,
reduce the connected load. Altitude derating power with connected loads for normal operation is listed as below:

Because fans lose efficiency with altitude, force air-cooled equipment will have a smaller derating.
The UPS is equipped with a fan for cooling. Place the UPS in a well-ventilated area. Maintain minimum clearance of
4 in. (100 mm) in front of the UPS and 12 in. (300 mm) in the back and on the sides of the UPS for heat dissipation
and maintenance.
