the electrical power supply for a device in this connected series
fails, the input of the failed device becomes highly resistive. As
a result, the 4...20 mA standard signal fails.

To ensure electromagnetic compatibility (EMC) the functional earth
must be connected to earth with a short line (max. 1 m). Functional
earth must have a cross-section of at least 1.5 mm².
