Install a Drive to Conform to the EMC Directive

Install drive models 2xxxB, 2xxxC, 4xxxB, and 4xxxC with this procedure to comply with the EMC Directive when the drive is a single unit or installed in a larger device.

  1. Install the drive on a grounded metal plate.
  2. Wire the drive and motor.
  3. Ground the wire shielding on the drive side and motor side.
    Figure 1. Wiring the Drive and Motor
    • Drive
    • 10 m (32.8 ft) maximum
    • Motor
    • Metal conduit
    • Grounding wire
    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 wire 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.

    • Shielded wire
    • Motor
    • Motor cable
    • Cable clamp
    • Grounding wire
  5. To maintain compliance with IEC/EN 61000-3-2 on drive models 2004, 4002, and 4004, install an AC reactor or a DC reactor. Refer to DC Reactor to select a DC reactor.
    Note:

    • The terminal block for the drive main circuit and the terminal block for the DC reactor have different shapes. The drive has a European-style terminal block, and the DC reactor has a round terminal block. Correctly prepare the ends of the wiring.

    • Ground the DC reactor (option) on the back of the mounting base. Remove all paint from the mounting surface of the control panel.
