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 with‐
out 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.
