2.2 Installation Preparation
2.2.1 Location
To extend the UPS life, the chosen place must offer:
Convenient wiring
Adequate operator access area
Good ventilation to meet the heat dissipation requirements
No corrosive gas, such as sulfur 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
2.2.2 Environmental Requirement
UPS room
The UPS is designed for indoor installation, which should be installed in a clean and well-ventilated environment, to
keep the ambient temperature within the specifications.
The internal fans provide 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
