Wiring
Please note:
} Information given in the " Technical details [ 9] " must be followed.
} The outputs 13­14, 23­24, 33­34 and 43­44 are safety contacts.
} To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details).
} Calculation of the max. cable runs 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.
} Do not switch low currents using contacts that have been used previously with high cur­
rents.
