Outputs 13-14, 23-24, 33-34, 43-44, 63-64, 73-74, 83-84, 93-94 are safety contacts;

output 51-52 is an auxiliary contact (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).
