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
RU
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.
