5. Safety instructions
DANGER
Danger of electric shock.  Before
removing the housing cover and before
installing the electrics, switch off all supply
circuits as well as the mains fuse and
secure them against being accidentally
switched back on again. Attach a warning
sign in a clearly visible place.
DANGER
Danger if the relevant regulations for
electrical installations are not observed.
 Before removing the upper part of the
housing/fan insert and before installing the
electrics, switch off all supply circuits as
well as the mains fuse and secure them
against being accidentally switched back
on again. Attach a warning sign in a clearly
visible place.
 Be sure to observe the relevant regu-
lations for electrical installation; e. g.
EN 50110-1, in Germany this is particularly
VDE 0100, with the corresponding parts.
 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, 3x 1.5 mm² or 5x 1.5 mm².
 The units may only be operated using
the voltage and frequency shown on the
rating plate.
 Unit may also be energized even when
at a standstill and may be switched on
automatically by sensors (time delay,
humidity etc.) or by the thermo switch in the
motor winding. Maintenance and fault
finding only permissible when carried out
by trained specialists.
 The degree of protection stated on the
rating plate is only guaranteed if installation
is undertaken correctly and if the
connecting cable is correctly guided
through the cable grommet (The grommet
must completely enclose the cable
sheathing). The fan insert must also be
engaged and the housing cover installed.

DANGER of fire spreading
In the event of a fire, there is a risk
of the fire spreading
● if an incorrect connecting cable is
connected to the ER housing. Always
use the right duct material for the
ER housing  chapter 11.1.
● if incorrect ceiling compound is used for
exhaust air systems with an intermediate
ceiling (aeroduct, PAM-GLOBAL RML
or ceiling penetration). Ensure that the
gap remaining between the main duct
and wall or ceiling is fully sealed with
non-flammable materials resistant to
deformation, such as concrete, cement
mortar or plaster.
● if the seal with the brickwork or wall
boards is incorrect. If used outside the
shaft, ensure that the gap remaining
between the connection duct and brick-
work/wall boards is fully sealed with
non-flammable materials resistant to
deformation, such as concrete, cement
mortar or plaster and for the wall boards,
special fire protection filler.
● if the metal exhaust socket [5] is
incorrectly connected to the connection
duct. 3 steel blind rivets are stipulated
for the connection with the exhaust
socket. These must not impair the
shutter function. Before commissioning,
ensure that the shut-off shutter is
moving with ease.
● if the metal shut-off shutter [3] is not
correctly inserted and screwed down in
the exhaust socket. During installation,
it is essential that the shut-off shutter is
correctly positioned and screwed down.
The soldered strut must be correctly
inserted and the shutter must move with
ease.
