The basic environmental requirements for the operation of the UPS system:
•
Ambient temperature range: from +5...+40 °C (+5 ...+35 °C for 240 kVA and 360 kVA PF 0.9 models).
•
Recommended operating range for VRLA batteries: +20...25 °C.
•
Maximum relative humidity: 95%, non-condensing.
•
Recommended relative humidity range: 20 - 60 %.
You must arrange ventilation of the UPS room. Sufficient amount of air cooling is needed to keep the
maximum room temperature rise at desired level.
•
To limit the temperature rise to a maximum of +5 °C, the required airflow is 600 m
losses.
•
To limit the temperature rise to a maximum of +10 °C, the required airflow is 300 m
losses.
An ambient temperature from +20 to +25 °C is recommended to achieve a long life of the UPS and
batteries. The cooling air entering the UPS must not exceed +40 °C. Avoid high ambient temperature,
moisture, and humidity.
For ventilation requirements, see 93PM G2 heat rejection in the following table.

If you install an external maintenance bypass (MBS):
NOTE:
•
The UPS static bypass input (X2) and UPS rectifier input (X1) must have external isolators to isolate
these feeds from the external MBS input during service operations.
•
Do not connect the external MBS input to a different source than the UPS static bypass input (X2).
