: Install these options as required.
NOTE
• To prevent an electric shock, always earth (ground) the motor and inverter.
• Do not install a power factor correction capacitor or surge suppressor or capacitor type filter on the inverter's output side.
Doing so will cause the inverter to trip or the capacitor and surge suppressor to be damaged. 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. In this case, activating the EMC filter may minimize interference. (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.

Overview
Refer to page
The life of the inverter is influenced by the ambient temperature.
The ambient temperature should be as low as possible within the permissible range.
Incorrect wiring may lead to damage of the inverter. The control signal lines must be kept fully away from the main circuit lines to protect them from noise.
The built-in EMC filter can reduce the noise.
In this inverter, a DC reactor and common mode choke are built in to suppress harmonics and to improve the power factor.
Must be within the permissible power supply specifications of the inverter.
Three-phase AC power supply
Molded case circuit breaker (MCCB), earth leakage circuit breaker (ELB), or fuse
Must be selected carefully since an inrush current flows in the inverter at power ON.
Magnetic contactor (MC)
AC reactor (FR-HAL)
High power factor converter (FR-HC2)
Install this to ensure safety.
Do not use this to start and stop the inverter. Doing so will shorten the life of the inverter.
Install this to suppress harmonics and to improve the power factor.
An AC reactor (FR-HAL) (option) is required when installing the inverter near a large power supply system (1000 kVA or more). Under such condition, the inverter may be damaged if you do not use a reactor.
Select a reactor according to the applied motor capacity.
Suppresses the power supply harmonics significantly. Install this as required.
Power regeneration common converter
Power regeneration converter
(MT-RC
)
Brake unit (FR-BU2, FR-BU
, BU
)
Resistor unit (FR-BR , MT-BR5
)
Provides a large braking capability. Install this as required.
Allows the inverter to provide the optimal regenerative braking capability.
Install this as required.
USB connection
Noise filter
(FR-BSF01, FR-BLF)
Induction motor
Contactor
Example) No-fuse switch (DSN type)
A USB (Ver. 1.1) cable connects the inverter with a personal computer.
Parameter setting and monitoring can be performed by FR Configurator 2.
A USB memory device enables parameter copies and the trace function.
Install this to reduce the electromagnetic noise generated from the inverter. The noise filter is effective in the range from about 0.5 MHz to 5
MHz.
A wire should be wound four turns at maximum.
Connect a squirrel-cage induction motor.
Connect this for an application where a PM motor is driven by the load even while the inverter power is OFF. Do not open or close the contactor while the inverter is running (outputting).
When PM motor control is selected, a PM motor can be driven.
PM motor
Compatible with the FR-F846-01160(55K) or lower.
Compatible with the FR-F846-01800(75K) or higher.
