Grounding
If the bus terminal is mounted on a DIN rail (see Figure 4-33), the shield clamp
makes large-area contact with the rail via an internal spring. To connect the cable
shield with local ground, a connection between the DIN rail over as short a
distance as possible to local earth is adequate.
