► The funtional earth (FE) must be connected to the protective earth (PE) or to
the potential equalisation� The system installer is responsible for implementing
this connection�
► Connecting cables and signal lines must be installed in such a manner that
inductive or capacitive interference do not impair the automatic functions�
► Install automation equipment and related operating elements in such a way that
they are protected against unintentional operation�
► Suitable safety hardware and software measures should be implemented for
the I/O interface so that a line or wire breakage on the signal side does not
result in undefined states in the automation device�
► Ensure a reliable electrical isolation of the low voltage for the 24 V supply�
Only use power supplies compliant with IEC 60 364-4-41 or HD 384�4�41 S2
(VDE 0100 part 410) �
► Fluctuations or deviations of the mains voltage from the rated value must not
