• Ground Fault Interrupter:

Select a ground fault interrupter not affected by high frequencies. To

prevent malfunctions, the current should be 200 mA or higher and

the operating time 0.1 s or longer.

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 (600 kVA 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.

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 cata-

log.
