Connection of the Smoke Exhaustion System
!
The relevant roofing guidelines and any lightning
protection requirements must be adhered to!
When installing the ventilation and smoke
extraction bonnet, please observe the flat
roof guidelines of the Central Association of
the German Roofing Trade.
Furthermore, the installer must have a qualification in the
field of the trade association guidelines for power-operated
windows, doors and gates. In addition, they must be fami-
liar with the relevant work regulations, accident prevention
regulations and generally recognised rules of technology
(e.g. VDE regulations, DIN standards, etc.) to such an extent
that they can put the system into a safe working condition.
Cable length and cross-section depend on the drive type
and number of drives. Cable length and cross-section can
be calculated with the following formula:
The drive line is monitored for line breaks and
short circuits via a line end module.
Calculation formula
For required core cross section of a supply cable
A = Cable cross section in mm
L = Cable length in m
I = Current of the connected drives in A
∆
U = Voltage drop on the line = 2 V DC

Connect the device whilst it is voltage-free!
Switch off the power supply and secure it
against being switched on again!

Installation of the smoke exhaustion system
When installing the smoke exhaustion system, the relevant
technical rules must be adhered to. The installation work is
to be carried out by specialists from the roofing and window
construction trade.
The louvre window must always be installed vertically. No
mechanical tension may be applied on the louvre window
during installation.
The ventilation and smoke exhaustion hood is mounted on
the respective substructure using suitable fixing materials.
The gasket must be installed as far as possible underneath
the smoke exhaustion opening holes. If insulation or roofing
sheeting provided by the customer is installed, fastening
screws (e.g. for cap strips) must not protrude more than
20 mm into the duct of the smoke exhaustion hood. The
opening of the ventilation hood cover must not be reduced
in size.

The smoke exhaustion system must not
be subjected to shocks, jolts or vibrations.
Unauthorised changes to the system are
prohibited. The manufacturer is not liable
for damages resulting from unauthorised
changes.

During installation and storage on site,
the smoke exhaustion system must be
protected against moisture, such as we-
ather.
The electrical performance features of
the drives are specified in the techni-
cal data sheets of the respective louv-
re windows or on the product labels of
the drives. They must be compared with
the performance features of the Control
Units and adapted accordingly.
