DANGER Danger from electric shock/The
unit will be damaged if installed incorrectly
with too long a power cable.
If the cable feed is too long inside the housing,
the fan insert cannot be installed correctly. The
power cable may be damaged when inserting the
fan unit.
Area for mains connection labelled: Lay wires
according to the contour.
Note that the max-
imum spacing to the connection terminal box is
7 cm. Do not cut the power cable inside the hous-
ing too short.
NOTICE Damage to the unit if connected in-
correctly.
For example, if an electric load is connected to
terminal 4 or if connected to 2 phases.
Connect the unit according to the wiring dia-
grams:
Wiring diagram [
}
23] . Do not connect
additional consumers to terminal 4.
NOTICE Risk of damage to unit in the event of
short-circuits.
Cut off and insulate PE conductor and individual
cable cores that are not required!
Notes
• Make electrical connections when installing the
housing.
• Observe permitted duct cross-section of max.
1.5 mm².
• Only connect the unit to a permanent electrical
installation.
• The degree of protection is only guaranteed:
• for intended installation;
• if the power cable is properly inserted through
the stepped grommet;
• with the fan insert correctly engaged in the
surface-mounted housing;
• with the cover screwed, closed and locked in
place.
10.1 Electrically connecting the unit
1. Prior to accessing the connection terminals,
switch off all supply circuits. Switch off mains
fuse, secure against being accidentally
switched back on and position a visible warn-
ing sign.
2. Cut off and insulate PE conductor and indi-
vidual cable cores that are not required!
3. Remove power cable’s sheathing and cut to
length: Electrical connection [ } 18] .
4. Wire power cable to the terminal box accord-
ing to the wiring diagram: Wiring diagram
[ } 23] . Terminal 1 is marked with a triangle.
5. Mark the fan type and connection type on the
wiring diagram in the AP/APB housing.
6. This prevents mistakes during final installation,
for example, if different fan inserts are fitted in
the system.
Recommendation : Keep these mounting instruc-
tions until the final assembly in the flush-mounted
housing.
