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

EN55011 (1991) Class A Group 1 (1

Environment, restricted distribution)

General precaution

EMI filter and AC motor drive should be installed on the same metal plate.

Please install AC motor drive on footprint EMI filter or install EMI filter as close as possible to

the AC motor drive.

Please wire as short as possible.

Metal plate should be grounded.

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.
