6 Mounting preparations
sion measures are needed (L or C components
or RC modules, protection diodes, varistors) be-
cause these values may be exceeded.
• Recommendation: When operating on switches
with a glow lamp, wire an X2 capacitor (220 nF/
250 V) to zero. The capacitor is to be provided
by the customer.
• Storage: Store unit exclusively in a dry location
(-20 to +50 °C).

6 Mounting preparations
6.1 Wall
Use mounting material suitable for base and of
sufficient dimensions. Ensure sufficient supply air.
The prescribed minimum distances to the
wall and the ceiling shown in the figure must
be observed.
1. Make sure the housing has a level base.
2. Fit wall breakthrough or drill core hole. Min-
imum diameter, 105 mm.
230 V
50 Hz
Level 1: 27 dB(A)
Level 2: 32 dB(A)
IP X5
0.7 kg
Recommendation: Fit WH 100 wall sleeve.
Fit wall breakthrough with minimum diameter
115 mm.
Use ZM 11 mounting plate for rectangular
wall breakthroughs.
3. Lay power cable (flush-mounted) up to install-
ation site, see above for spacing. Feed the
power cable at least 110 mm out from the
wall.
6.2 Ceiling
1. Perform installation preparations as described
in Chapter Wall [} 21].
DANGER Danger of short-circuits and
damage to unit if condensation builds up in
the fan housing.
Thermally insulate ventilation ducts properly. Al-
low for a condensation drain or condensate col-
lector in the riser.
6.3 Duct
1. Deburr edges on the inside of the duct.
2. Perform installation preparations as described
in Chapter Wall [} 21].
