Installation and Commissioning
Shielding of the Fieldbus Trunk Using the R* Electronic Component in
Intrinsically Safe Segments
The shield (terminal S) of the fieldbus trunk is internally connected to the grounding point.
Grounding and Shielding *D0-MIO-Ex12*
Shielded cables for the valve or sensor are not required.
The device provides a grounding terminal for connecting to an equipotential bonding.
Connection to Equipotential Bonding System
All shield connections are internally connected to the "Shield/Screen GND" grounding terminal.

Caution!
Risk of electric shock or property damage from inadequate grounding
If you fail to connect all metal parts of the device to protective local earth correctly, this could
result in potential equalization currents. These currents could hurt operating personnel or
cause property damage.
The grounding terminal is not a safety earth: Do not use the grounding terminal to ground
exposed metal parts.
Ground exposed metal parts of the device separately. Ensure that a correct grounding is
guaranteed at all times.
