in the enclosure
Fig. 3:
Never direct the cold airflow at active components
Exercise particular caution with the airflow from the
blowers of built-in electronic components (cf. Fig. 3).
Components for targeted air routing are available as
accessories – please refer to the chapter on “System
climate control” in the Rittal Catalogue.
Fig. 4:
Targeted air routing inside the enclosure
Note:
Risk of condensation!
When arranging the components inside
the enclosure, please ensure that the
cold airflow from the air/water heat ex-
changer is not directed at active com-
ponents. Please also ensure that the
cold airflow is not directed at the warm
exhaust airflow from active components
such as converters. This may lead to an
air short-circuit and therefore prevent
adequate climate control, or may even
cause the air/water heat exchanger’s
internal safety devices to cease cooling
operation.
Note:
When using an air duct system, care must
be taken to ensure that it is laid straight and
without kinks wherever possible. This mini-
mises the resistance to the cold air flow.
It is important to ensure even air circulation
inside the enclosure. Under no circum-
stances should air inlet and outlet openings
be obstructed, otherwise the cooling per-
formance of the unit will be reduced. Ensure
a suitable distance from electronic compo-
nents and other installed enclosures so that
the required air circulation is not obstructed
and prevented.
One cold air outlet from the air/water heat
exchanger must be kept open at all times
when operating with the air duct, to prevent
the accumulation of cold air inside the unit.
