EMI Filter Installation

All electrical equipment, including 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 drive and EMI filter are installed and wired

according to user manual:

1. EN61000-6-4

2. EN61800-3: 1996

3. EN55011 (1991) Class A Group 1

General precaution

EMI filter and drive should be installed on the same metal plate. It is recommended to install the

drive on the filter.

Please wire as short as possible. Metal plate should be grounded. The cover of EMI filter and 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.

1. Use the cable with shielding (double shielding is the best). The shielding on both ends of the motor

cable should be grounded with the minimum length and maximum contact area.

2. Remove any paint on metal saddle for good ground contact with the plate and shielding as shown in

figure 1.

3. The shielding net of motor cable and the plate must be connected correctly. The shielding net on the

two ends of motor cable should be fixes by the metal saddle and the plate. See figure 2 for correct

connection.
