CE-EMC Installation Guidelines
You are required to satisfy the EMC directive (2004/108/EC) when using a WL200 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.

WL200-185H needs to be installed in a metal cabinet and add ferrite core at the input
cable to meet category C1. Unless otherwise category C2.
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 20m, use output choke to avoid unexpected 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 encompass 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.
Allow the effective shield area of these lines to remain as large as possible; i.e., do
not strip away the shield (screen) further away from the cable end than absolutely
necessary.
