VENTILATION AND COOLING

Fig. 5.5-1 Installation on plain floor
The heat produced by the UPS is transferred to the environment by its ventilation.
Cooling air enters the cabinets through the air inlet (grids) located at the bottom and exhausted through
the outlet on the roof.
A suitable ventilation or cooling system must be installed to extract the heat from the UPS room.
NOTE !
Insufficient space on both sides of the UPS in respect to the wall can cause a
dangerous increase of the internal operating temperature.
Do not put anything on the top of the cabinet.
If the UPS is placed on a raised floor, the airflow for UPS cooling should enter from underneath the UPS,
through the appropriate aperture on the raised floor.
If the UPS runs in a dusty environment, we recommend strongly to install filters on the air inlet of the
UPS room.
In this case it should be considered that these filters can cause reduced speed at the air inlet.
The size of the air inlet has therefore to be dimensioned accordingly.
Contact your Local Distributor or one of the Service Centre, which will help you to find valuable
solutions.
