2.3 UPS Location
2.3.1 Positioning the UPS
Choose a location for the UPS that offers:
• Easy connection to inputs, outputs and auxiliary equipment
• Enough space to service the UPS
• Air circulation sufficient to expel heat produced by UPS
• Protection against moisture and excessive humidity
• Protection against dust and other particulate matter
• Compliance with fire prevention regulations and practices
• Operating environment temperature of 74-80°F (23-27°C) for maximum battery life
2.3.2 Environmental Considerations
Before installing the Liebert
®
EXM
™
, verify that the UPS room satisfies the environmental
conditions stipulated in 7.2 - UPS Environmental Requirements, paying particular attention to
the ambient temperature and air exchange system.
The UPS unit should be installed in a cool, dry, clean-air environment with adequate ventilation to
keep the ambient temperature within the specified operating range 32°F to 104°F (0°C to 40°C).
For optimal UPS system performance and service life, maintain the operating temperature within
the range of 74-80°F, (23-27°C).
The Liebert
®
EXM
™
is cooled by internal fans. Cooling air enters the unit through the front of the
unit and is exhausted out the top. To permit proper air flow and prevent overheating, do NOT
block or cover the ventilation openings or blow air down onto the unit. The UPS requires 24 in.
(610mm) ventilation clearance above the unit.
See Table 26 for details on heat dissipation.
