Surge suppressors

Ground fault interrupter:

Select a ground fault interrupter not affected by high frequencies. To prevent
malfunctions, the leakage current sensitivity 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.
