DANGER
H
azard due to lack of effectiveness of the protective device
The dangerous state may not be stopped in the event of non-compliance.
b
Prevent the formation of a potential difference between the load and the protec‐
tive device.
b
If y
ou connect loads to the OSSDs (safety outputs) that then also switch if con‐
trolled 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 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 connections of the loads and
those of the corresponding protective device.
