Surge suppressors
• 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.
For the details of the peripheral devices, refer to the catalog.
• Parameter List

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.
