Avoiding any potential difference between load and protective device
If y
ou 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 0V connections of
these loads and those of the corresponding protective device separately and also
directly to the same 0V terminal strip. In the event of a fault, this is the only way to
ensure that there can be no potential difference between the 0V connections of the
loads and those of the corresponding protective device.
