3.2 Function
The roof-mounted fan in conjunction with the corre-
sponding inlet filter(s) is used to dissipate heat loss from
enclosures and ventilate the enclosure, thereby protect-
ing temperature-sensitive components. This is achieved
via the direct infeed of ambient air, the temperature of
which must be lower than the admissible enclosure inte-
rior temperature.

ciently with the following accessories:
* Not compatible with 3140.140.
3.2.2 Safety devices
The fan is equipped with a thermal winding protection for
protection against overload.
3.2.3 Filter mats
The roof-mounted fan is supplied with four class G3 filter
mats installed. The filter must be checked regularly de-
pending on the level of dust exposure, and replaced as
necessary.
3.3 Proper use
Rittal roof-mounted fans were developed and designed
in accordance with the state of the art and the recog-
nised rules governing technical safety. Nevertheless, if
used improperly, they may pose a threat to life and limb
or cause damage to property. The unit is only intended

liable for any damages caused as a result of improper
