5.2.5 Shielding/potential equalization
• You achieve optimum shielding against disturbances if the shielding is connected on both
sides (in the cabinet and on the device). If potential equalization currents are expected in
the plant, only ground shielding on one side, preferably at the transmitter.
• When using in hazardous areas, you must observe the applicable regulations.
Separate Ex documentation with additional technical data and instructions is included
with all Ex systems as standard.
5.3 Potential equalization
Hazardous area applications: Connect all devices to the local potential equalization.
Observe the applicable regulations.
