instruCtions
Routing cables and electrical connection
Routing or installing electrical lines and connections may
be performed only by approved specialist companies. Never
operate drives, Control Units, operating elements and sen-
sors at operating voltages and connections contrary to the
specifications of the manufacturer.
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.
The power line on-site must be secured se-
parately and provided all poles separators.
After opening of the system housing voltage
carrying parts are exposed. The system must
be separated from the power supply and bat-
tery voltage before each intervention in the
Control Unit of the system.

Area of application
The control device shall only be used according to its inten-
ded use. For additional applications consult the manufactu-
rer or his authorized dealer.
Installation
These instructions address expert and safety-conscious
electricians and / or qualified personnel knowledgeable of
the electrical and mechanical installation of drives and con-
trol systems.
Mounting material
The required mounting material must be modified to fit the
occurring load.
Crush and shear points
To avoid injuries,
crushing and shear points
between
casement and frame must be secured
against entrapment
up to an installation height of 2,5 meters above the
floor
with appropriate measures. This can be achieved e.g.
by using contact-based or contactless protective devices
against entrapment, which stop the motion through contact
or through interruption by a person. A warning symbol at
the opening element must indicate this clearly.

iNstructioNs
It is important to follow these instruc-
tions for the safety of persons. These
instructions shall be kept in a safe place
for the entire service life of the products.
Risk of crushing and entrapment!
Electromotive operated windows can
close automatically!
The compressive force is absolutely
sufficient to crush fingers in case of
carelessness.
01
The planning and calculation of the
wiring system is the responsibility of
the builder or his agent or the authori-
zed constructor and must be performed
according to the statutory provisions.

All relevant instructions shall be observed for the in-
stallation, specifically:
• VDE 0100 Setting up high-voltage systems up to 1000 V
• VDE 0815 Wiring cables
• Specimen Guideline on Conduits German designation
(MLAR).
We recommend using exclusively sys-
tem components by
a
umüller
, because
their compatibility is carefully checked
in the factory.
a
umüller
shall not assume
liability for the system-compatible func-
tioning of third party components.
Applications and connections other than
explicitly described in these instructions
require the express written consent of
a
umüller
. Utilization of applications and
components not expressly authorized by
a
umüller
are considered as unintended
use even if their perfect functioning is
proven at commissioning (e.g. approval
under building law).
