3. Fit foam strip supplied to socket in centre
( fig. E).
4. For a surface-mounted electrical connec-
tion, drill out the housing segment [2.1]
(diameter 11 mm,  fig. H).

7. Installation

7.1 Installing housing

1. Insert housing [2] into wall breakthrough /
wall sleeve (TOP must be at top).
2. Align housing horizontally and mark the
3 dowel holes ( arrows, fig. H).
3. Remove housing [2], drill M6 dowel holes
with a diameter of 6 mm and insert dowels.
4. Push cable grommet [3] carefully out of
housing and remove. Alternatively, for a
surface-mounted electrical connection,
leave cable grommet [3] in housing and
take cable grommet [4] out of housing.
Danger of short circuits and
NOTICE
damage to unit. Water will
penetrate if the power cable is
incorrectly fed into the fan
housing or if the cable
grommets are not fitted
correctly [3]/[4].
Cut off cable grommet cap such
that the cable grommet fits
tightly round the power cable.
Do not trim the cap by more than
5 mm. Fit cable grommet(s)
correctly, seal if required.
5. Insert cable grommet [3]/[4] in housing [2].
6. Guide the power cable into the connection
area such that the cable grommet fits
around the cable sheathing completely.

7.2 Electrical connection

Danger to life from electric
shock.
Prior to access to the
DANGER
connection terminals switch off
all supply circuits. Switch off
mains fuse, secure against
being accidentally switched
back on and position a visible
warning sign.
Risk of damage to unit in the
NOTICE
event of short-circuits.
Insulate PE conductor and
unneeded cable cores.
Always note the relevant specifica-
tions for electrical installations and
when fitting equipment. In Germany
observe DIN VDE 0100 and the
corresponding parts in particular.
1. Only lay single cable cores in the unit. To
do this, remove the sheathing of the power
cable in the connection area. Strip single
cable cores to 9 to 10 mm.
2. Insert housing [2] into wall breakthrough /
wall sleeve and secure with 3 screws.
Do not insert the housing such that it is
twisted or crushed. Make sure you use
mounting material which is sized for the
purpose.
3. Connect the power cable on the terminal
block [13] to the electricity supply  wiring
diagrams in Chapter 16.
4. Check position of cable grommet [3] or [4].
It must be well sealed.
