Attention !
Inadequate shielding can lead to operating errors. Therefore, observe the following
points.
Data line shielding
·
Connect shielding as shown in Fig. 25.
·
Lay the shielding at both ends.
·
Secure the shielding on the entire surface.
·
Do not damage or squeeze any wires.
·
Ensure that the shielding covers as much of the individual wires as possible in
the unit.

The shielding connection for all INTERBUS
devices always alternates between a direct PE connection
and a PE connection made by means of a 47 nF capacitor.
The capacitor is active when the jumper in the device next
to the terminal block is removed (see Fig. 26).
