3-6 Installing the Converter
590D DC Digital Converter - HA467078
Protective Earth Connections (PE)
IMPORTANT: The VSD 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 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 Chapter 12: “Certification for the Converter” - Screening & Earthing (cubicle mounted,
Class B).
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 Chapter 11: “Technical Specifications” - Power
Details, using a suitable fuse or circuit breaker (a circuit breaker, e.g. RCD, ELCB, GFCI, is not
recommended,
