D.2 European Standards
Installation Method
Verify the following installation conditions to ensure that other devices and machinery used in combination with this
drive also comply with EMC guidelines.
1. Install an EMC noise filter to the input side specified by Yaskawa for compliance with European standards.
2. Place the drive and EMC noise filter in the same enclosure.
3. Use braided shield cable for the drive and motor wiring, or run the wiring through a metal conduit.
4. Keep wiring as short as possible. Ground the shield on both the drive side and the motor side.

5. Make sure the ground conductor complies with technical standards and local safety rules. When an EMC filter is
installed, the leakage current exceeds 3.5 mA. Therefore according to IEC61800-5-1, at least one of the
conditions below must be satisfied:
a) The cross-section of the protective earthing conductor must be at least 10 mm2 (Cu) or 16 mm2 (Al).
b) The power supply must be disconnected automatically in case of discontinuity of the protective earthing
conductor.
