7.4 The air ventilation
The filter modules are cooled by ventilation. Therefore the air must be able to
move free above and below the filter module. If the filter module is mounted in an
electrical enclosure or in other industrial enclosures, it must be guaranteed, that an
adequate airflow streams through the filter module to diminish the the danger of
overheating of filter module and surrounding components.
If other heat sources for example the frequency converter are installed in the same
enclosure, the heat that is generated by both components must be considered
when sizing the cooling for the enclosure.
The filter modules must be mounted on the wall in that way, that the air is guided
through the air gap between wall and filter module (see figure 25). At an Installa-
tion on rails without rear panel, the filter module is not cooled adequate, because
of the wrong air flow. This is only allowed with the optional rear panel.
Figure 25 shows the correct mounting of the filter module:
