with the AC reactor suppresses harmonics more effectively.
The input power factor of the Inverter is improved by suppressing the harmonics of the
input current of the Inverter.
Connection
Connect the DC reactor to the internal DC power supply of the Inverter after shutting
OFF the power supply to the Inverter and making sure that the charge indicator of the
Inverter turns OFF.
Do not touch the internal circuitry of the Inverter in operation, otherwise an electric
shock or burn injury may occur.
Wiring Method
Please refer to Chapter 9 for more detailed information on AC and DC Reactors.
