automatically.
5. When the power cable is surface installed at
position “S”, knock out the housing segment at
the nominal opening and cut small recesses
into the cross struts on the rear of the lower
part of the housing to route the ducts.
NOTICE Danger of short-circuits and damage
to the unit. If the power cable is incorrectly
fed or if the cable grommet is not fitted cor-
rectly, water may penetrate into the fan hous-

Pierce the cable grommet so that it tightly seals
the power cable. Guide the surface-mounted or
flush-mounted cables correctly into the intended
cable grommet.
6. Pierce a round opening in the cable grommet
with a grommet puncher.
7. Guide the power cable into the terminal com-
partment such that the cable grommet fits
around the cable sheathing completely.
