■ Installing the External EMC Noise Filter
Drive models BxxxA, 2xxxA, and 4xxxA must align with the conditions in this section to comply with EN 61800-
3:2004/A1:2012.
Connect an EMC noise filter that complies with European standards as specified by Yaskawa to the input side
(primary side). Refer to External EMC Noise Filter Selection on page 185 to select the correct EMC noise filter.
Use this procedure to install an EMC noise filter to make equipment 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
D - Metal conduit
E - Grounding wire
Figure 5.11 Wiring the Drive and Motor
Note:
• Use a braided shield cable for the drive and motor wiring or put the wires through a metal conduit.
• Keep the wire as short as possible. The maximum wiring length between the drive and motor is:
–BxxxA, 2xxxA, 4xxxA: 10 m (32.8 ft)
• 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 or local safety standards.
A - Braided shield cable
B - Metal plate
C - Cable clamp (conductive)
