Formula to calculate
the required wire cross-section of a infeed 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)
Comply with the local regulations and directives for
fi re behaviour of
building materials and building components (E30, E60, E90) and erec-
tion of power installations with rated voltages below 1000V!
Recommendation:
In choosing a cable, select the next higher wire cross section to antici-
pate possible later changes to the system (e.g. replacement of drives
with greater current consumption or extension of the SHEV or venti-
lation line.

CONNECTION
Connecting drive cable
• Avoid any installation area with large temperature dif-
ferences, risk of water condensation
• Close to the window (shall be easily accessible later on
for repair work)
• Ensure that a later removal of the connection cable is
possible
• Observe maximum cable length of drives (standard
length approx. 3 meters)

RUN
Check safety of the assembled system and perform test run
and commissioning.
Safety check:
• Connect operating voltage
• Re-check fastenings (casement bracket, frame
bracket) and re-tighten if necessary
Performing test run:
• visual check of casement motion
• stop immediately in case of mulfunction
• make sure there is no collision with facade construction
and, if necessary, correct assembly or re-confi gure
