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.
