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.

Choose suitable motor cable and precautions

Improper installation and choice of motor cable will affect the performance of EMI filter. Be sure to observe the following precautions when selecting motor cable.
