Layout of the components in the enclosure
Observe the air flows from the internal fans of installed
electronic components. For installation, it is important
to ensure that the airflows of fans and built-in electronic
components do not have a negative influence on one
another (air short-circuit). The corresponding minimum
distances between the fan and component must be
observed in order to ensure unhindered air circulation.
4.3
Fitting the EC fan-and-filter unit or out-
let filter
The EC fan-and-filter unit or outlet filter is mounted on a
vertical panel of the enclosure:
◾ For this purpose, the appropriate door, side or rear
panel must be cut out using the supplied drilling
template.
The EC fan-and-filter unit is generally fitted in the lower
part of the enclosure, and the outlet filter in the upper
part.
4.3.1
Cutting out the enclosure
◾ Stick the self-adhesive drilling template supplied to
the envisaged position on the door, side or rear panel
of the enclosure.
Lines indicating the dimensions of cut-outs and drilling
specifications for mounting and fixing of the fan (only
necessary for sheet metal thickness 2.5 mm and
above) are to be found on the drilling template. See
also fig. 10 and fig. 11, page 13.
Risk of injury!
Carefully deburr all cut-outs to prevent
injuries caused by sharp edges.
◾ Make the cut-outs including the line width as per the
drilling template
◾ Deburr the cut-outs.

Fitting the EC fan-and-filter unit
– The fan may be fitted without tools, by simply snap-
ping into the preconfigured mounting cut-out.

– Make sure that the clips have snapped into place
properly to guarantee secure mounting.
– From a sheet metal thickness of 2 mm, the clips
should be pressed in individually.
– From a sheet metal thickness of 2.5 mm, the EC
fan-and-filter unit must be screwfastened in addition
(tightening torque, see section 11 "Cut-out/drilling
dimensions").
– To drill the lower holes, it is necessary to remove the
louvred grille as shown in fig. 2.

– If transporting, it is necessary that you screw-fasten
the fan to prevent it from falling out of the mounting
cut-out.
– The fan-and-filter unit is a rotating component that
may transfer vibrations and oscillations.
Appropriate measures to decouple vibration must be
taken in advance by the company responsible for the
overall plant or system.
– The protection category can be increased by means
of the following accessories:
– IP55 by using a pleated filter or a hose-proof hood.
– IP56 by using a hose-proof hood.
Note:
To increase the protection category, a pleat-
ed filter or hose-proof hood must be used
for the EC fan-and-filter unit and outlet filter.

Notes on electrical connection
When performing the electrical connection, it is impor-
tant to observe all valid national and regional regula-
Rittal EC fan-and-filter unit assembly and operating instructions
