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
EN55011 (1991) Class A Group 1
General precaution
1. EMI filter and AC motor drive should be installed on the same metal plate.
2. Please install AC motor drive on footprint EMI filter or install EMI filter as close as possible to the AC
motor drive.
3. Please wire as short as possible.
4. Metal plate should be grounded.
5. The cover of EMI filter and AC motor drive or grounding should be fixed on the metal plate and the
contact area should be as large as possible.
