nstruCtions
The types of cable, cable lengths and cross-sections shall
be selected in accordance with the manufacturer’s technical
data. If necessary, the cable types shall be coordinated with
the competent local authorities and energy supply com-
panies. Low-voltage lines (24 V DC) shall be routed
separate from the high-voltage lines. Flexible cables may
not be flush-mounted. Freely suspended cables shall be
equipped with strain reliefs.
Clamping points shall be checked for tightness of threa-
ded connections and cable ends. Access to junction boxes,
clamping points and external drive control systems shall be
ensured for maintenance work.
Commissioning, operation and maintenance
After the installation and after each modification in
the set up all functions shall be checked with a trial run.
After the installation of the system is completed the
end-user shall be instructed in all important operating
steps.
If necessary, he must be advised of all remaining risks /
dangers.
The end-user shall be instructed in intended use of the
drives and, if necessary, the safety instructions. The end-user
shall be specifically instructed that no additional forces,
except for the pressure and tension in the opening and
closing direction of the casement, may be applied to the
spindle, chain or lever of the drive.
The power line on-site must be secured sepa-
rately and provided with all poles separators.
After opening of the system housing voltage
carrying parts are exposed. The system must
be separated from the power supply and ac-
cumulator voltage before each intervention in
the Control Unit of the system.
Cables must be laid such way that they cannot
be sheared off, twisted or bent during operati-
on. It is recommended to perform an insulati-
on measurement of the system’s line network
and to document this.

Post warning signs!
During the proper assembly of drives with mounting
elements at a window, and the connection to an external
Control Unit, the interfaces resulting from mechanical and
electrical performance characteristics of single elements
shall be observed.
Other persons must be kept away from
the casement when a hold-to-run switch
(pushbutton) is operated or when a
window, which has been opened by a
smoke and heat exhaust system, is clo-
sing!
The operating element of hold-to-run
switches must be installed within di-
rect view from the window, but apart
from moving elements. If the switch is
not a key-operated switch it must be
installed at a minimum height of 1,5 m
and inaccessible to the public!
Do not allow children to play with
permanently mounted control devices
and keep remote controls out of reach
for children!

Before working on the system it must be com-
pletely disconnected from the power supply
and emergency power supply (e.g. accumu-
lators) and secured against unintentional re-
activation. While working in the Control Unit
the workplace must be secured to prevent
unauthorized access. It must be ensured that
unauthorized personnel are unable to open
the Control Unit.

Check all functions of the system before
releasing it for operation.
The installation instructions of system components (smo-
ke detector, natural smoke and heat exhaust ventilators,
drives, etc.) are part of the documentation for the complete
system and must be kept accessible for authorized quali-
fied personnel, together with the installation and operating
instructions, for the entire service life of the system.
