Option 3 - Multiple points of grounding
In installations where potential equalisation is known to provide a consistent, low impedance ground
plane throughout the plant, the fieldbus cable may be grounded at more than one point.
This is illustrated in Figure 12 where the trunk and spur cable shields are interconnected at the cable
shield busbar (1) and the busbar is connected to local ground (2).
