3.4. Site & Environment Consideration
Usually the life expectancy of the DC UPS system is 8 to 10 years. The optimal life expectancy
of the DC UPS system 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 DC UPS:
a.
The DC UPS should be located in a place with adequate ventilation (refer to the
specification of the heat dissipation of the DC UPS). Should the DC 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 DC 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 (exceptions to space requirements
would occur with approved layouts). Adequate space, a minimum of 60cm (2’)
[recommended 1m (3’)], should also be allowed at the top of the DC UPS system to allow for
proper heat dissipation and ventilated through the top openings (optional ventilation booth is
available upon request).
c.
Do not place any objects on the top of the DC UPS that might obscure the ventilation. Do
not place the DC UPS near any heat source, or machinery, which may produce metallic
particles, dust or powder. Do not place the DC UPS near equipment that will produce
corrosive substances or vapor.
d.
Do not place the DC UPS below the shower of a fire extinguishing system (optional drip
shield available). Abnormal conditions of the DC UPS should be protected by a cutoff from
the power supply.
e.
The user is required to guarantee the temperature and humidity values of the site into
which the DC UPS will be installed, meet the required and published manufacturer
specifications. The DC UPS should be installed within the range allowed by these
specifications. The DC UPS is capable of continuous normal operation within a temperature
range of 0°C (32°F) to 40°C (104°F). For optimal performance and reliability the
recommended environment temperature is best at 25°C, with humidity < 80% non-
condensing.
f.
The floor loading capacity should be sufficient to endure the weight of the DC UPS and
and its internal batteries.
g.
Walls, ceilings, floors or anything near to the DC UPS should be constructed of non-
combustible materials. A portable fire extinguisher should be accessible nearby.
