HF equipotential bonding in the system

Make sure that there is a suitable equipotential bonding between the system, the control cabinet, the machine structure, the cable ducts, and the drives.

Connect the individual sections together in an HF-compatible manner.

From an electrical safety perspective, the PE busbar is the star point. However, the PE connection does not replace either the HF grounding or the shielding.

In terms of EMC, it is advantageous if the mounting plate is used as a star point with respect to HF equipotential bonding.

Perform the following measures for a suitable HF equipotential bonding:

• Connect the PE busbar to the mounting plate in an HF-compatible manner.
• Connect the sheet metal cable ducts to the control cabinet in an HF-compatible manner.
• Connect the cable ducts to the mounting plate in the control cabinet using a high frequency litz wire.
• Connect the parts of the sheet metal cable ducts together in an HF-compatible manner.
• Connect the sheet metal cable ducts to the gearmotor in an HF-compatible manner.
