7.3 Cabinet air conditioning
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.
