Peripheral Devices - Mitsubishi Electric FR-F820-00046 Instruction Manual

NOTE
• To prevent an electric shock, always earth (ground) the motor and inverter.
• Do not install a power factor correction capacitor, surge suppressor, or capacitor type filter on the inverter's output side. Doing
so will cause the inverter shut off or damage the capacitor or surge suppressor. If any of the above devices is connected,
immediately remove it. When installing a molded case circuit breaker on the output side of the inverter, contact the
manufacturer of the molded case circuit breaker.
• Electromagnetic wave interference:
The input/output (main circuit) of the inverter includes high frequency components, which may interfere with the
communication devices (such as AM radios) used near the inverter. To minimize interference, enabling the built-in EMC filter
or installing an external EMC filters is effective. (Refer to
• For details of options and peripheral devices, refer to the respective Instruction Manual.
• A PM motor cannot be driven by the commercial power supply.
• A PM motor is a motor with permanent magnets embedded inside. High voltage is generated at the motor terminals while the
motor is running. Before closing the contactor at the output side, make sure that the inverter power is ON and the motor is
stopped.

NOTE
• Select an MCCB according to the power supply capacity.
• Install one MCCB per inverter. For the use in the United States or Canada, refer to "Instructions for UL and cUL" in the
Instruction Manual (Startup) or Instruction Manual (Hardware) to select an appropriate fuse or MCCB.
