Rittal enclosure cooling unit 11
5 Installation
EN
 Under no circumstances should the air inlet and outlet
openings of the cooling unit be obstructed. Only in this
way is it possible to ensure that the maximum cooling
output is available.
 Please ensure that the cold airflow from the cooling
unit is not directed at active components.
Fig. 5: Never direct the cold airflow at active components
 If appropriate, install components to divert the air.
 When installing in a dismantled door or side panel,
please ensure that it cannot fall over when installing
the cooling unit in the mounting cut-out.
5.3.2 Mounting options
In principle, there are three different options for installing
the cooling unit on an enclosure door or side panel.

Key
1 External mounting
2 Partial internal mounting
3 Full internal mounting
– External mounting: All of the cooling unit is outside the
enclosure.
– Partial internal mounting The cooling unit chassis is in-
side the enclosure, while the cover and the louvred
grilles are outside.
– Full internal mounting: All of the cooling unit is inside
the enclosure. Only the louvred grilles project on the
outside.
Your chosen installation option will ultimately depend on
how much space you require inside and outside of the
enclosure. The various mounting options have no influ-
ence on the cooling output of the cooling unit, which re-
mains the same in all cases.
– If there are a large number of components installed in-
side the enclosure, external mounting or partial in-
ternal mounting of the cooling unit may be appropri-
ate. In such cases, the space inside the enclosure may
be insufficient for full internal mounting, or it may not
be possible to guarantee adequate cooling of all com-
ponents inside the enclosure.
– If the space surrounding the enclosure is limited,
full internal mounting may be suitable, so as to keep
essential escape routes clear.
Note:
The pictures in this chapter illustrate the in-
stallation of the cooling unit in an enclosure
door. Installation in a side panel is carried out
in the same way.
Note:
– Full installation of the 6 kW cooling unit is
not possible.
– On an enclosure with 500 mm depth, the
unit may only be externally mounted on the
side panel.
