Connections between the Dupline signal and earth potential will cause malfunctions and
are not permissible. In addition, check for the correct polarity of the Dupline signal.
In order to meet the requirements for protective low voltage, VDE0100, Part 410, should
be observed and put into practice during installation. For reasons of safety and space
requirements, mains cables may not be routed through the same installation box.
In cases of mixed operation with AC voltage at one input and DC voltage at the other,
the above requirements are not fulfilled.
