The C-rail can be used as required by the application, for example, as a protective earth (PE).
In this case, the PE connection of each power supply module must be connected to the
mounting rail via an additional PE terminal, which is available as an accessory.
The C-rail is not interrupted by the modules of the XNE ECO-products. It is connected through
the modules’ connection level. But, an access to the C-rail is not possible.

Warning
It is permitted to load the C-rail with a maximum of 24 V. Not 230 V!
Note
For information about introducing a XI/ON station into a ground reference system,
please read Chapter 8, Page 149.
