Electrical installation
Prevent the formation of a potential difference between the load and the protective
device!
If you connect loads that are not reverse-polarity protected to the OSSDs or the safety
outputs, 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.
This is the only way to ensure that, in the event of a defect, there can be no potential
difference between the 0 V connections of the loads and those of the corresponding
protective device.
