Peripheral Devices E - 4
Peripheral Devices
The following peripheral devices may be required to be mounted between the AC main circuit power supply and the Drive
input terminals R/LI, S/L2, and T/L3.
For more details on peripheral devices, contact the manufacturer.
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 transform of large capacity (600 kVA or more) or to improve the power factor on
the power supply side.
Fig E.5
Noise filter
Use a noise filter exclusively for the Drive if radio noise generated from the Drive causes other control devices to malfunction.
CAUTION
Never connect a general LC/RC noise filter to the drive output circuit.
Never connect a phase-advancing capacitor to the input or output sides, or a surge suppressor to the output
side of the Drive. When magnetic contactor is installed between the Drive and the motor, never turn it on or off
during operation.
