4 Planning before installation
The equipment must be installed in upright position and it requires space both front and back side
to enable cooling airflow. The cooling air enters the unit through air inlets in the front and exits from
the rear of the unit. The required minimum clearance from unit rear to an obstruction is 150 mm. For
service and maintenance, 500 mm of empty space above the UPS unit is also required.

It is required to arrange ventilation of the UPS room. Sufficient amount of air cooling is needed to
keep the max. room temperature rise at desired level:
• Temperature rise of max. +5°C requires the airflow of 600 m³ per 1 kW of losses.
• Temperature rise of max. +10°C requires the airflow of 300 m³ per 1 kW of losses.
An ambient temperature of 15 to 25 Celsius degrees is recommended to achieve a long life of the
UPS and batteries. The cooling air entering the UPS must not exceed +45 °C. Avoid high ambient
temperature, moisture and humidity.
The floor material should be non-flammable and strong enough to support the heavy load.
