Table 3-3: Air Conditioning Or Ventilation Requirements During Full Load Operation - Eaton 93PR Installation And Operation Manual

The basic environmental requirements for operation of the UPS system are:
• Ambient Temperature Range: from +0°C to +30°C, To ensure that your UPS functions well,
please operate it in an environment with an ambient temperature ranging between 0 - 30°C.
If the ambient temperature exceeds 30°C, the UPS should be de-rated by 12% for every
increase of 5°C in the temperature; the maximum ambient temperature should not exceed
50°C as UPS operating with loads in high-temperature environments for a long time will result
in the reduction of the battery life. For example, if the UPS working environment temperature
is 35°C, the load must be less than 88%. If it exceeds 90%, the UPM will shut down.
• Recommended Operating Range: from +20°C to +25°C
• Maximum Relative Humidity: 95%, non condensing
The room where the UPS is placed must meet the following air circulation requirements:
• For 300KWUPS, air flow need be not lower than 3400M
• For 600KWUPS, air flow need be not lower than 6800M
• For 1200KWUPS, air flow need be not lower than 13600M
The UPS ventilation requirements are shown in the following table:
