Hitachi hitachi series inverter 用户手册

You are required to satisfy the EMC directive (2004/108/EC) when using an WJ200 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.

WJ200-110L and 150H needs to be installed in a metal cabinet and add ferrite core at 
the input cable to meet category C1. Unless otherwise category C2. 

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.
