Follow the steps below to connect cables to the SCALANCE W786.
1. Connect the cables to the appropriate contacts. (Position A in the figure above) You have
the following options:
– Connect cables preassembled with a connector (Ethernet, antennas) by inserting the
connector into the appropriate socket. Secure antenna cables by tightening the sleeve
nut of the connector (key size SW8). You will find more information on this topic in the
sections "Connection for Industrial Ethernet" and "Connections for external antennas".
– 48 V DC power supply. Use the connector supplied with the SCALANCE W786. For
details of the terminal assignment, refer to the section "Connectors for the power
supply".
– 12 - 24 V DC or 110 - 230 V AC power supply. With these power supplies, you require a
power supply adapter (do not ship with the SCALANCE W786). You will find more
information in the section "Connecting a power supply adapter".
2. Fit a strain relief clamp to the connected cable. The toothed part of the clamp must
enclose the cable completely (as shown by position B in the figure above).
3. Press the strain relief clamp into the housing until the cable is located completely in the
opening in the housing seal (position C in the figure above).
