IMPORTANT
The drive and filter (if fitted) must be permanently earthed. Each conductor used for
permanent earthing must individually meet the requirements for a protective earth
conductor.
For installations to EN 60204 in Europe:
• For permanent earthing, the drive requires either two individual incoming protective earth conductors (<10mm²
cross-section), or one conductor (10mm² cross-section) connected to an independent protective earth/ground
point near the drive.
• Run the motor protective earth/ground connection in parallel with the motor supply conductors, ideally in the
same conduit/screen/armour, and connect to an independent protective earth/ground point near the drive.
Refer to Appendix B: “Certification” - EMC General Installation Considerations.
Caution
On the Frame 5, both the Master and Slave drives must be individually earthed.
