The outputs are switched in the circuit diagram with the out-put relays Q, S or SN.The jump destination has a special position for the input contacts and the jump locationfor the output relays. These are used for structuring a circuit diagram → Section "Work-ing with contacts and coils", page 133.Following is a description of how to wire various contacts and coils for the variousrelay types and function blocks (inputs) in the circuit diagram.easyE4 11/18 MN050009 EN www.eaton.com 133
