• 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 sec. or more.
Example : • NV series by Mitsubishi Electric Co., Ltd. (manufactured in
1988 and after)
• EGSG series by Fuji Electric Co., Ltd. (manufactured in 1984
and after)
• AC and DC reactor :
Install an AC reactor to connect to a power supply transformer of large
capacity (600kVA or more) or to improve power factor on the power
supply side.
• Noise filter:
Use a noise filter exclusively for inverter if radio noise generated from the
inverter causes other control devices to malfunction.
NOTE
1. Never connect a general LC/RC noise filter to the inverter output circuit.
2. Do not connect a phase advancing capacitor to the I/O sides and/or a
surge suppressor to the output side.
3. When a magnetic contactor is installed between the inverter and the
motor, do not turn it ON/OFF during operation.
For the details of the peripheral devices, refer to the catalog.
