The DC supply is always earth-referenced and must not be generated by
an auto-transformer.
To ensure safe isolation of the user interface, the DC power supply must be
provided with safe isolation. See Subsection 2.1.3.
In the case of supply cables > 10m, protection elements must be fitted at
the device input in order to protect against lightning (surge voltage).
The DC supply voltage must be connected to the ground/shield of the NC
for EMC and/or functional reasons. For EMC reasons, this connection
should only be made at one point. As a rule, the connection is provided as
standard in the S7-300 I/Os. If this is not the case in exceptional
circumstances, the ground connection should be made to the grounding rail
of the NC cabinet; see also /EMC/ SINUMERIK, SIROTEC, SIMODRIVE,
EMC Guideline (06.99).
