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 contami-
nants. Install the UPS indoors in a clean environment, where it is away from window and door. Main-
tain 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:
Altitude (meters)
1,000
1,500
2,000
2,500
3,000
3,500
4,000
4,500
5,000
Based on density of dry air = 1.225kg/m ^3 at sea level, +15ºC. Since fans lose efficiency with altitude, forced air cooled
equipment will have a smaller derating
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.
5. Connect to External Battery Pack
