To prevent the fan and/or electric
components from malfunctioning as
a result of reverse polarity voltages
and induction (incorrect ignition or
glowing/flaring of LED, energy-
saving or neon lamps), the fan and
electric components connected in
parallel, such as room lighting,
should be connected via a double-
pole switch.
DANGER
Danger to life from electric shock.
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 warning sign.
DANGER
Danger to life 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.
Note that the maximum spacing to the
terminal box is 7 cm. Do not cut the
power cable inside the housing too
short.
CAUTION
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!
