Single UPS Installation and Commissioning
2.2.2
Location
To extend the UPS life, the place chosen must offer:
The UPS must be installed vertically, on a level and even surface
Convenient wiring
Adequate operator access area
Adequate ventilation to meet the heat dissipation requirement
No corrosive gas, such as sulphur dioxide and so on
No excessive moisture or heat source
No excessive dust
Compliance with fire-fighting requirements
Operating temperature compliant with the specifications, see Table 1-2 for details
2.2.3
Environmental Requirement
UPS room
The UPS is designed for indoor installation, which should be installed in a clean and well-ventilated environment, so as to keep
the ambient temperature within the specifications.
The internal fans provide the forced air cooling for the UPS. Cooling air enters the UPS through the ventilation holes on the front
panel, and exhausts the hot air through the back ventilation holes. Therefore, do not obstruct the ventilation holes. Maintain at
least 200mm clearances between the front, rear, side panels of the UPS and the wall or adjacent equipment (see Figure 2-1), so
as not to obstruct the UPS ventilation and heat dissipation. Otherwise, the UPS internal temperature will rise, which will shorten
the UPS life.
If necessary, an indoor exhaust fan should be installed to keep the indoor temperature from rising. An air filter should be used
where the UPS is to operate in a dusty environment.

Note
The UPS should be installed only on the concrete surface or other non-flammable surfaces.
Note: for exchanging the UPS
Power Module or the Battery
