Caution!
Risk of condensation!
When arranging the components inside
the enclosure, please ensure that the
cold airflow from the cooling unit is not
directed at active components. Please
also ensure that the cold airflow is not
directed at the warm exhaust airflow
from active components such as con-
verters. This may lead to an air short-
circuit and therefore prevent adequate
climate control, or may even cause the
cooling unit's internal safety devices to
cease cooling operation.
Fig. 3: Never direct the cold airflow at active components
Air diversion components are available as accesso-
ries – please refer to the Rittal catalogue.
It is important to ensure even air circulation inside the
enclosure. Under no circumstances should air inlet
and outlet openings be obstructed, otherwise the
cooling performance of the unit will be reduced.
Ensure the distance "x" (see Fig. 4) from electronic
components and other installed enclosures so that
the required air circulation is not obstructed and pre-
vented.

Fig. 5: Installation method
To this end, cut the side panel or door of the enclo-
sure as per the drilling template included with the
supply, and drill the relevant holes.
Note:
Units of type SK 3302.xxx can only be either
externally mounted or fully internally moun-
ted.
Units of type SK 3332.xxx can only be either
externally mounted or partially internally
mounted.
For mounting the units SK 3328.xxx,
SK 3329.xxx and SK 3332.xxx in the TS side
panel or rear panel, we recommend the use
of enclosure panel fasteners TS 8800.071
(see Rittal Catalogue).
