Please note:
} Information given in the "Technical details" 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).

} 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 connect undesignated terminals.
} The power supply must comply with the regulations for extra low voltages with safe
electrical separation (SELV, PELV) in accordance with VDE 0100, Part 410.
