Installing the External EMC Noise Filter
Drive models 4xxxA must meet conditions in this section to comply with EN 61800-3:2004+A1:2012.
Connect an EMC noise filter to the input side (primary side) that complies with European standards as specified
by the manufacturer.
Use this procedure to install an EMC noise filter to make machinery and devices added to the drive comply with
the EMC Directive.
1.
Install the drive and EMC noise filter on the same grounded metal plate.
2.
Wire the drive and motor.
3.
Ground the wire shielding on the drive side and motor side.
A - Drive
B - 10 m (32.8 ft.) maximum
C - Motor
Note:
• Use a braided shield cable for the drive and motor wiring or put the wires through a metal conduit.
• The maximum wiring length between the drive and motor is 10 m (32.8 ft.). Keep the cable between the drive and motor as
short as possible.
• Keep the grounding wire as short as possible.
4.
Use a cable clamp to ground the motor cable to the metal plate.
Note:
Make sure that the protective ground wire complies with technical specifications and local safety standards.
