AC reactors and DC reactors decrease surges in current and improve the power factor on the input side of the drive.

Connect an AC reactor or a DC reactor to the input side (primary side) in these conditions:

  • To decrease harmonic current or improve the power factor of the power supply

  • When there is switching of phase advancing capacitor

  • With a large capacity power supply transformer (600 kVA or more).

Note:

  • You can use an AC reactor and DC reactor together.

  • When you connect a thyristor converter (for example, a DC drive) to the same power supply system, use an AC reactor.

  • The main circuit terminal block for the drive and the terminal blocks for the AC and DC reactors come in different shapes. The drive has a European-style terminal block, and the AC and DC reactors have a circular terminal block. Correctly prepare the ends of the wiring.

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