DIN rail modules do not have any protective earth conductor terminals.<br />

However they are conductively connected to the DIN top-hat rail after<br />

they are engaged and locked onto it. The DIN rail modules thereby receive<br />

signal grounding. �-"6.1-Grounding Concept" on page 38<br />

Assuming that the power limits are observed, the internal electronics of DIN<br />

rail modules and the attached sensors may also be supplied from a single<br />

power supply.<br />
