Figure 9-11 Front Connector Assignments

1)Observe permissible potential difference between sensor ground and reference potential of modules or between sensor grounds.

2)Two-wire transducer

3)Only required to switch off the tripping current without broken wire detection; 0 V at L-.

4)Connect L- to the central ground point (reference potential).
