• X = clearance at the back of the UPS cabinet

• Y = clearance at the top of the UPS cabinet

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

per 1 kW

of losses.

• Temperature rise of +10 °C maximum requires the airflow of 300 m

per 1

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
