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).
