• Magnetic contactor
Mount a surge protector on the coil. When using a magnetic contactor to start and stop the drive, do
not exceed one start per hour.
• Ground fault interrupter
Select a ground fault interrupter not affected by high frequencies. To prevent malfunctions, the
current should be 200mA or more and the operating time 0.1 second or more.
• AC and DC reactor
Install a reactor to connect to a power supply transformer of large capacity (600 kVA or more) or to
improve the power factor on the power supply side.
• Noise filter
Use a noise filter exclusively for the drive if radio noise generated from the drive causes other
control devices to malfunction.
