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).
