If users are to operate the AC motor drive in coordination with the EMI filters manufactured by
DELTA, consult the above chart for the appropriate I/O terminals’ of the applicable filters.
!
The filter will cause high leakage current. We recommend the grounding is required.
Installation
All electrical equipment, including AC motor drives, will generate high-frequency/low-frequency noise
and will interfere with peripheral equipment by radiation or conduction when in operation. By using an
EMI filter with correct installation, much interference can be eliminated. It is recommended to use
DELTA EMI filter to have the best interference elimination performance.
We assure that it can comply with following rules when AC motor drive and EMI filter are installed
and wired according to user manual:
EN61000-6-4
EN61800-3: 1996 + A11: 2000
