3.2 Assembly and Connectors

Securing the Housing

There are two ways of securing the housing:

● Use the holes in the housing to screw the device to the wall or on a horizontal

surface.

● Install the SCALANCE W788 on a 90 mm long, vertically mounted piece of

standard rail (S7-300). In this case, the standard rail serves as an

adapter between the wall and SCALANCE W788. If you want to install the

SCALANCE W788 along with a PS791-1PRO, a 150 mm long standard rail is

necessary.

Connectors for the Power Supply and for Ethernet

The SCALANCE W788 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 IP65 protection is lost. A suitable protective cap is available as an ac-

cessory. If you do not use the M12 connector, the supplied protective cap must be

fitted to retain IP65 protection.
