Wiring
Please note:
} Information given in the "Technical details [ 735]" must be followed.
} Outputs 13-14, 23-24, 33-34, 43-44 are safety contacts; outputs 51 -52 are auxiliary
contacts (e.g. for display).
} Auxiliary contact 51-52 shouldnot be used for safety circuits!
} To prevent contact welding, a fuse should be connected before the output contacts (see
Technical details [ 735]).
} 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.
