Illustration 5: Grounding Principle
For EMC-compliant installation
• Establish electrical contact between the cable shield and the drive enclosure by using metal cable glands or by using the clamps
provided on the equipment.
• Use high-strand wire to reduce burst transient.
• Do not use pigtails.
POTENTIAL EQUALIZATION
Risk of burst transient when the ground potential between the drive and the control system is different. Install equalizing cables
between the system components. Recommended cable cross-section: 16 mm
