Site & Environment Consideration
The designed function of the UPS is to provide a safe, clean and independent electrical supply
free from random variations, disturbances or interruptions of the utility mains. The UPS will
provide a constant power source, which is regulated in both voltage and frequency. When the
utility mains are not available, the UPS will provide optimal back-up time depending on the
capacity connected battery bank.
Usually the life expectancy of the UPS is 8 to 10 years. The optimal life expectancy of the UPS
can be achieved by careful consideration of the site and environment.
The following precautions and recommendations should be checked when considering the site
and environment for the UPS:
a.
The UPS should be located in a place with adequate ventilation (refer to the specification of
the heat dissipation of the UPS). Should the UPS be installed in a sealed room, care must
be taken to ensure adequate heat evacuation is provided.
b.
Void space is not required on all sides of the UPS system, but adequate space, a minimum
of 1m (3’), should be allowed at the front for the door to open and a minimum of 60cm (2’)
should be allowed on the right side to allow for the door to open and removal of the side
panels for operation or maintenance purposes. Adequate space, a minimum of 60cm (2’)
[recommended 1m (3’)], should also be allowed at the top of the UPS system to allow for
proper heat dissipation and ventilated through the top openings (optional ventilation booth
is available upon request).
c.
The battery banks require access to front only. A minimum of 1m (3’) should be allowed at
the front to allow for the door to open and removal of the side panels for operation or
maintenance purposes.
