CAUTION!
Check strap for strain relief
Possible consequence: Material
damage.
The ribbon cable and its base cannot
be mechanically stressed. Hence it is
essential when mounting the con‐
troller in the control panel, that the
check strap (part number 1035918) is
fitted for strain relief and mechanical
fixing. Without the check strap, the
ribbon cable or its base could be
damaged if they were to fall out of the
top part of the controller housing.
