two dowel holes, drill the dowel holes Ø 6
mm and insert the dowels.
NOTICE
Danger of short circuits and
damage to unit. If the power
cable is incorrectly fed or if
the cable grommet is not fitted
correctly, water may penetrate
into the fan housing and the
degree of protection cannot
be guaranteed.
Pierce the cable grommet [2] or

tightly clasps the power cable
(cut in a round shape, no slot).
Guide the surface- or recessed-
mounted cables correctly into
the intended cable grommet.
3. Carefully press out the cable grommet [2]
or [3] from the housing [4], then remove
and pierce a round hole in the cable
grommet by means of a grommet puncher.
Use cable grommet [3] for surface
installation and cable grommet [2] for
recess installation.
4. Reinsert the removed cable grommet in
a professional manner, provide sealing
on site if necessary.
5. Guide the power cable into the connection
area such that the cable grommet fits
around the cable sheathing completely.
