14 Rittal enclosure cooling unit
These fastening clamps ensure that the cooling unit is
directly in contact with the mounting cut-out of the en-
closure door over the entire height.
 If applicable, re-attach the door or side panel including
cooling unit to the enclosure, if not mounted directly
on the enclosure.
5.3.5 Mounting the cooling unit externally on a
500 mm deep enclosure
In principle, external mounting on the side panel is car-
ried out in the same way as described in section 5.3.4
"External mounting of the cooling unit". However, please
note the following differences:
– Six threaded bolts are required for installation, rather
than four.

2 Rear of cooling unit
– The unit with the threaded bolts is lowered into the rel-
evant holes, rather than on the mounting cut-out.
– No fastening clamps are fitted into the rear of the unit.
5.3.6 Partial internal mounting of the cooling unit
 At the front of the cooling unit, pull the top louvred
grille away from the mounting clips on the cover, and
place or lay it down somewhere safe.

cooling unit.
Note:
The description in this section applies to ex-
ternal mounting of the cooling unit on the
side panel of a 500 mm deep enclosure. Ex-
ternal mounting on deeper enclosures is also
possible with this type of installation.
