5 Safety instructions regarding in-
stallation, operation, cleaning and
maintenance
DANGER Risks for children and people
with reduced physical, sensory or mental cap-
abilities or a lack of knowledge.
Unit may only be installed, commissioned,
cleaned and maintained by persons who can
safely recognise and avoid the risks associated
with this work.
DANGER Danger of electric shock from
operating the unit when not fully mounted.
Electric components are a potential source of
electric shock.
If the unit is open, all off the supply circuits must
be switched off (mains fuse off), secured against
being accidentally switched back on and a visible
warning sign must be attached.
Only operate the unit when it is completely in-
stalled.
DANGER Danger if the relevant regula-
tions for electrical installations are not ob-
served.
Before removing the housing cover or removing
the fan insert and before installing the electrics,
switch off all supply circuits, switch of mains fuse
and secure it against being accidentally switched
back on again. Attach a warning sign in a clearly
visible place.
Be sure to observe the relevant regulations for
electrical installation; e.g. DIN EN 50110-1. In
Germany, particularly observe VDE 0100, with
the corresponding sections.
A mains isolation device with contact openings of
at least 3 mm at each pole is mandatory.
Only connect unit to permanently wired electrical
installation and with NYM-O or NYM-J cables,
depending on the unit variant, 3 x 1.5 mm² or 5 x
1.5 mm².
Units may only be operated using the voltage and
frequency shown on the rating plate.
Unit may be energized even when at a standstill
and may switch on automatically due to sensors
(time delay, humidity etc.). Maintenance and fault
finding only permissible when carried out by qual-
ified electricians.
The degree of protection stated on the rating
plate is only guaranteed if installation is under-
taken correctly and if the connecting cable is cor-
rectly guided through the stepped grommet (The
grommet must completely enclose the cable
sheathing). The fan insert must also be engaged
and the housing cover installed.
DANGER Danger due to fire transmission
if an incorrect connection duct is connected to the
housing. Always use the correct cable material
for the respective housing.
.
if an incorrect ceiling compound is used for ex-
haust air systems with an intermediate ceiling
(ceiling barrier system)
. Ensure that the gap re-
maining between the main duct and wall or ceil-
ing is fully sealed with non-flammable materials
resistant to deformation, such as concrete, ce-
ment mortar or plaster.
