Rittal enclosure cooling unit
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. 8:
Never direct the cold airflow at active components (ex-
ample illustration)
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.

Mounting options
Essentially, there are two options for fitting the cooling
unit on an enclosure door or side panel.

External mounting

Internal mounting
– External mounting: All of the cooling unit is outside the
enclosure.
– Internal mounting: All of the cooling unit is inside the
enclosure. Only the louvred grilles project on the out-
side.
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 of the cooling
unit may be appropriate. In such cases, the space in-
side the enclosure may be insufficient for internal
mounting, or it may not be possible to guarantee ade-
quate cooling of all components inside the enclosure.
– If the space
surrounding the enclosure
is limited, in-
ternal mounting may be appropriate to keep essential
escape routes clear.
5.3.3
Make a mounting cut-out in the enclosure
In order to mount the cooling unit on the enclosure, a
suitable mounting cut-out must be made in the door or
side panel of the enclosure.

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:
The dimensions of the mounting cut-outs
can be found in section 12.1 "Representa-
tion of mounting cut-outs".
