Figure 2-1 Example: Direct Grounding Of Afd4 / Afd4 (Fm) - Siemens SIMATIC AFD4 Product Information

Direct grounding
The shielding of the bus lines is grounded directly in the hazardous area and in the safe
area. This is possible if the equipotential bonding PA runs from the FDC 157 couplers (in the
safe area) to the field devices (in hazardous areas), which means if a corresponding
equipotential bonding conductor is installed.
Note
Direct grounding
The braided shielding of the connection cables must be guided under the shielding clamps of
the active field distributors.
