Recommended Peripheral Devices
It is recommended that the following peripheral devices be mounted between the AC main circuit power supply and Varispeed V7 input terminals R/L1, S/L2, and T/L3.
• MCCB (Molded-case Circuit Breaker)/Fuse:
Always connect for wiring protection.
• Magnetic Contactor:
Mount a surge suppressor on the coil. (Refer to the table shown below.) When using a magnetic contactor to start and stop the
Inverter, do not exceed one start per hour.

10. Specifications
• 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.
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.
