Protective Earth Connections
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
PE
Connect the
drive's PE
terminal to an
independent
earth/ground
star point.
Connect this
earth/ground
star point to
Protective
Earth.
For installations to EN 60204 in Europe:
• For permanent earthing, the converter 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.
• Connect the drive to the independent earth/ground
point.
Refer to Appendix B: “Certification” - EMC General
Installation Considerations.
NOTE The 720/800A chassis requires two
individual incoming protective earth
conductors to the filter using the two
M8 terminals provided. BOTH MUST
BE CONNECTED to protective earth.
Protect the incoming mains supply, detailed in
Appendix E: “Technical Specifications” - Power
Details, using a suitable fuse or circuit breaker (a
circuit breaker, e.g. RCD, ELCB, GFCI, is not
recommended,
refer to “7Earth Fault Monitoring
Systems”, page 3-39.)
