12 Rittal enclosure cooling unit
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. In principle, the mounting
cut-out is identical for all three mounting options. A spe-
cial mounting cut-out is only required for external mount-
ing on the side panel of a 500 mm deep enclosure.
 Using the diagrams in section 12.1 "Representation of
mounting cut-outs", calculate the required dimensions
for your mounting cut-out .
 Drill all the required holes and make the mounting cut-
out.
 Carefully deburr all drilled holes and the cut-out to pre-
vent injuries caused by sharp edges.
5.3.4 External mounting of the cooling unit
 Cut the sealing tape in the dispatch bag to the re-
quired length so that it can be placed all the way round
the rear of the cooling unit once.
 Start by positioning the sealing tape on the bottom
edge, so that the joint between the two ends of the
sealing tape is likewise on the lower edge of the unit.
 Carefully stick the sealing tape as close to the edge as
possible on the rear of the cooling unit.
 Screw the four threaded bolts into the blind nuts in the
corners at the rear of the cooling unit.


Push the clip included with the supply into the relevant
hole at the top edge of the cooling unit at the rear.
This clip will prevent the cooling unit from falling out of
the mounting cut-out later on if it is not yet adequately
secured with the threaded bolt.

Note:
The dimensions of the mounting cut-outs
can be found in section 12.1 "Representation
of mounting cut-outs".
Caution!
Drilled holes and cut-outs that have not
been fully deburred may cause cut inju-
ries, particularly when assembling the
cooling unit.
Note:
The description in this section does not ap-
ply to external mounting of the cooling unit on
the side panel of a 500 mm deep enclosure.
This is described in section 5.3.5 "Mounting
the cooling unit externally on a 500 mm deep
enclosure".
