Appendix D
CE-EMC Installation Guidelines
D-1 CE-EMC Installation Guidelines
You are required to satisfy the EMC directive (2004/108/EC) when using an
MX2 inverter in an EU country.
To satisfy the EMC directive and to comply with standard, you need to use a
dedicated EMC filter suitable for each model, and follow the guidelines in this
section. Following table shows the compliance condition for reference.
D-1-1 Important notes
1. Input choke or other equipment is required if necessary to comply with
EMC directive from the harmonic distortion point of view (IEC 61000-3-2
and 4).
2. If the motor cable length exceeds 25 m, use output choke to avoid unex-
pected problem due to the leakage current from the motor cable (such as
malfunction of the thermal relay, vibration of the motor, etc.).
3. As user you must ensure that the HF (high frequency) impedance between
adjustable frequency inverter, filter, and ground is as small as possible.
• Ensure that the connections are metallic and have the largest possible
contact areas (zinc-plated mounting plates).
4. Avoid conductor loops that act like antennas, especially loops that encom-
pass large areas.
• Avoid unnecessary conductor loops.
• Avoid parallel arrangement of low-level signal wiring and power-carrying
or noise-prone conductors.
5. Use shielded wiring for the motor cable and all analog and digital control
lines.
