Cabinet air conditioning
5.2 Ventilation
The opening cross-sections specified in the table refer in each case to one device. If more
than one device is installed in a cabinet, the opening cross-section increases accordingly. If
the required openings cannot be made in the cabinet, the devices must be distributed across
several cabinets, which are separated from each other by means of partitions.
The warm air must be discharged via the top cover/hood or via side openings in the cabinet
at the level of the top of the device. The size of the opening cross-section must also be taken
into account here.
With degrees of protection higher than IP20 and if a hood is used, it may be necessary to
use an "active" hood. An "active" hood contains fans that blow the air current forwards. The
hood is closed, with the exception of the air outlet point.
If you choose an "active" hood, you must ensure that the fans are sufficiently powerful to
prevent air from accumulating in the cabinet. If air accumulates, the cooling capacity is
reduced. This can overheat and destroy the devices. The air capacity of the fans should at
least be equivalent to the device fan data.
