Wiring
Please note:
} Information given in the "Technical details" 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).
} Calculation of the max. cable length l
max
in the input circuit:
R
lmax
= max. overall cable resistance (see technical details)
R
l
/ km = cable resistance/km
} Use copper wire that can withstand 60/75 °C.
} Sufficient fuse protection must be provided on all output contacts with capacitive and in-
ductive loads.
