Wiring
Please note:
} Information given in the "Technical details [ 17]" must be followed.
} The output contacts 13-14, 23-24, 33-34 are safety contacts.
} To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 17]).
} Calculation of the max. cable length l

/km = cable resistance/km
} Use copper wiring with a temperature stability of 75 °C.
} To prevent EMC interferences (particularly common-mode interferences) the measures
described in EN60204-1 must be executed. This includes the separate routing of cables
of the control circuits (input, start and feedback loop) from other cables for energy trans-
mission or the shielding of cables, for example.
} Adequate protection must be provided on all output contacts with capacitive and inductive
loads.
