2-3. Setup the UPS
Before installing the UPS, please read below to select proper location to install UPS.
1.
UPS should be placed on the flat and clean surface. Place it in an area away from vibration,
dust, humidity, high temperature, flammable liquids, gases, corrosive and conductive
contaminants. Install the UPS indoors in a clean environment, where it is away from window
and door. Maintain minimum clearance of 100mm in the bottom of the UPS to avoid dust and
high temperature.
2.
Maintain an ambient temperature range of 0ºC to 45ºC for UPS optimal operation. For every
5ºC above 45ºC, the UPS will derate 12% of nominal capacity at full load. The highest working
temperature requirement for UPS operation is 50ºC.
3.
It’s required to maintain maximum altitude of 1000m to keep UPS normal operation at full
load UPS. If it’s used in high altitude area, please reduce connected load. Altitude derating
power with connected loads for UPS normal operation is listed as below:
4.
Place UPS:
It’s equipped with fan for cooling. Therefore, place the UPS in a
well-ventilated area. It’s required to maintain minimum clearance
of 100mm in the front of the UPS and 300mm in the back and two
sides of the UPS for heat dissipation and easy-maintenance.
