Revision B
4. Planning before installation
The equipment must be installed in upright position. The equipment requires space to front and
back to enable cooling airflow. Service and maintenance require 00 mm clearance on right
hand side. All cooling air enters at front and exits at unit rear. The required min. clearance from
unit rear to an obstruction is 20 mm. Because the service and user access is in the front there
should be reserved enough space (min 600 mm).
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. +°C requires the airflow of 600 m 3 per 1 kW of losses.
Temperature rise of max. +10°C requires the airflow of 300 m 3 per 1 kW of losses.
An ambient temperature of 1 to 2 Celsius degrees 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.
The floor material should be non-flammable and strong enough to support the heavy load. The
UPS has (4) leveling feet that should be used when finalising the installation. The diameter of a
single leveling foot is 29 mm.
