2.2. Pre-installation Preparation
• Install the UPS indoors in a controlled environment, where it cannot be accidentally turned O. The installation
environment should meet the specications listed in Specications on page 63.
• Place the UPS in an area of unrestricted air-ow around the unit, away from water, ammable liquids, gases,
corrosives, and conductive contaminants. Avoid direct sunlight.
NOTE: Operating the UPS in temperatures above 77°F (25°C) reduces battery life.
2.2.1. Installation Clearances
Maintain at least 4 in. (100 mm) clearance in the front and rear of the UPS. Do not obstruct the air inlets on the
front panel and rear panel of the UPS. Blocking the air inlets reduces ventilation and heat dissipation, shortening
the service life of the unit.
2.3. Installing the UPS
The UPS may be installed as a tower or in a rack, depending on available space and use considerations. Determine
the type of installation and follow the appropriate instructions. See Tower Installation or Rack Installation on next
page.
NOTE: For 16-kVA and 20-kVA models, the unit orientation is the same. See 1.2 on page 2, for the installed position.
NOTE: When the UPS does not need to be installed immediately, the UPS must be stored indoors to be
protected from the excessive moisture or over-temperature environment. The battery requires dry and
low temperature, well-ventilated environment for storage, and the most suitable storage temperature is
20 °C ~ 25 °C.
