Surge Suppressors
• 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 catalog.
