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
1. EMI filter and drive should be installed on the same metal plate. It is recommended to install the
drive on the filter.
2. 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.
