Figure 8. UPS cabinet clearances.
The basic environmental requirements for the operation of the UPS system are
as follows:
Ambient temperature range: from +0 to +40 °C
Recommended operating range: from +20 to +25 °C
Maximum relative humidity: 95%, non-condensing
It is required that ventilation of the UPS room is arranged. Sufficient amount of
air cooling is needed to keep the maximum room temperature rise at the desired
level:
Temperature rise of +5 °C maximum requires the airflow of 600 m
of losses.
Temperature rise of +10 °C maximum requires the airflow of 300 m
kW of losses.
An ambient temperature from +20 °C to +25 °C is recommended to achieve a
long life of the UPS and batteries. The cooling air that enters the UPS must not
exceed +40 °C. Avoid high ambient temperature, moisture, and humidity.
For ventilation requirements, see 93PS heat rejection in Table
