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 controller in the con‐
trol 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 dam‐
aged if they were to fall out of the
top part of the controller housing.
