Avoiding any potential difference between load and protective device
If you connect loads to the output signal switching devices (switching outputs) that
then also switch if controlled with negative voltage (e.g., electro-mechanical contactor
without reverse polarity protection diode), you must connect the 0 V connections of
these loads and those of the corresponding protective device separately and also
directly to the same 0 V terminal strip. In the event of a fault, this is the only way to
ensure that there can be no potential difference between the 0 V connections of the
loads and those of the corresponding protective device.
