neighboring mounting rails.

Connectors for the Power Supply and for Ethernet

The SCALANCE W78x is attached to Ethernet via a hybrid socket on the front of

the housing (position A in Figure 3.1). This port also has contacts for the operating

voltage.

Note

If you do not use the hybrid socket, this must be covered with a protective cap,

otherwise IP 65 protection is lost. A suitable protective cap is available as an

accessory (order no. 6ES7194-1JB10-0XA0). If you do not use the M12 connector,

the supplied protective cap must also be fitted to retain the IP65 degree of

protection.
