Operation of the power-operated window
When operating the power-operated window safety
instructions must be observed, specifi cally those pertaining
to commissioning, operation and maintenance.
Check the mounted system for its safety; perform test run
and commissioning.
Safety test:
• Connect operating voltage.
• Check fastening (frame brackets, casement brackets)
for fi rm fi t or tightening.
Test run:
• Visual inspection of casement movements.
• Stop immediately by malfunction!
• Pay attention to collision with facade construction and
correct installation, if required.
Risk evaluation:
Before operating a power-operated window to which
window drives were mounted, which were sold by the
manufacturer as incomplete machines according to instal-
lation declaration, the possible risk to ahazard of persons
must be determined, evaluated and minimized by taking
appropriate technical measures in accordance with the Ma-
chinery Directive. Separate documents for performing a risk
assessment can be downloaded from the homepage of

Formula to calculate
the required wire cross-section of a supply line
Calculation example
Available data:
• cut-off current per drive (i. e. 2 x 4.0A) from data sheet
• length to be bridged from the last window to the control unit
(i. e. 10 meters)

Laying and connecting the drive cable
• Avoid extreme temperature differences in the instal-
lation area (danger of condensation).
• Set clamping point close to window and ensure
accessibility.
• Ensure expansion possibilities of the drive and the drive
cable.
• Consider the cable length and the cross sections of
the drives supply lines.
24V
Observe current regulations and guidelines regarding
the “Fire behavior of building materials-circuit integrity
maintenance of electric cable systems“ (E30, E60, E90) and
the prescribed constructional regulations!
