Avoiding any potential difference between load and protective device
•
If y
ou connect loads to the output signal switching devices (safety outputs) that
then also switch if controlled with negative voltage (e.g., electro-mechanical con‐
tactor without reverse polarity protection diode), you must connect the 0 V connec‐
tions of these loads and those of the corresponding protective device individually
and 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 connec‐
tions of the loads and those of the corresponding protective device.
