Equipotential bonding
Regardless of the protective earth connection, it is essential that
low-impedance, HF-
capable equipotential bonding
is provided (see also EN 60204-1 or DIN VDE 0100-
540):
• Establish a connection over a wide surface area between the DRC drive unit and the
mounting rail.
• To do so, use a ground strap (HF litz wire), for example, to connect the DRC drive
unit and the plant's grounding point.
Example
• Do not use the cable shield of data lines for equipotential bonding.
