Material damages to electronics due to missing
functional earth!
Ensure that the functional earth is connected, as otherwise the electronics can
be destroyed by a potential difference between the operator display and the
control cabinet PC if the voltage supply is interrupted to only one device and
established again. A direct connection of the functional earth between the
operator display and the control cabinet PC is optimal. If the functional earth is
connected to a neutral point, the control cabinet PC and the operator display
have to be connected to this neutral point.
To avoid malfunctions, use only shielded cables and metallic or
conductive connector/coupling housings with large-area shield
support.
