24 VDC power supply?
Power supplies must conform to EN
60742:9/1995, EN 60950-1:2006/A11:2009 or
EN 50178: 10/97
Mains in accordance with
TN-S system?
This guarantees that there is no connection
between the neutral conductor and protective
conductor within the machine. With unbalanced
loads, e.g. TN-C systems, currents can be fed
back to the source via the PEN conductor and
the currents on the PEN are not zero. This can
lead to EMC problems.
