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
IT
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.
5. Connect To Transformer
Please do NOT connect transformer to output of the UPS. Otherwise, it will cause UPS internal
fault and force UPS to enter to fault mode. Please connect transformer to input of the UPS.
6. Connect to External Battery Pack
When connecting external battery packs, please be sure to connect polarity correctly. Connect
positive pole of battery pack to positive pole of external battery connector in UPS and negative
pole of battery pack to negative pole of external battery connector in UPS. Polarity
misconnection will cause UPS internal fault. It's recommended to add one breaker between
positive pole of battery pack and positive pole of external battery connector in UPS to prevent
damage to battery packs from internal fault.
The required specification of breaker: voltage ≧ 1.25 x battery voltage/set; current ≧ 50A
Please choose battery size and connected numbers according to backup time requirement and
UPS specifications. To extend battery lifecycle, it's recommended to use them in the
temperature range of 15ºC to 25ºC.
