Perform the following steps to connect a 48 V DC cable to a SCALANCE W786:
1. Connect the supplied connector to the 48 V DC cable. The figure above shows the
location of the socket in the housing and the contact assignment. The connector is safe
against polarity reversal and can only be inserted in the right-hand half of the housing
When connecting the cores, you should therefore make sure that the connector is
oriented as shown in the following figure.
