• Ambient temperature range: from +0...+40 °C(+0 ...+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
3
/h per 1 kW of losses.
• To limit the temperature rise to a maximum of +10 °C, the required airflow is
300 m
3
/h per 1 kW of 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.
