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.
The scope of the circuit depends on the related application. The
circuit is shown in Fig. 15, the terminal assignment in Tab. 5.
The supply of power to the sensors must be separate.
