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 be shut off 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 such a case, install the optional radio noise filter FR-
BIF (for use in the input side only) or line noise filter FR-BSF01 or FR-BLF to minimize interference. (Refer to
• For details of options and peripheral devices, refer to the respective Instruction Manual.
Overview
The life of the inverter is influenced by the surrounding air temperature.
The surrounding air temperature should be as low as possible within the
permissible range. This must be noted especially when the inverter is
installed in an enclosure.
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.
Must be within the permissible power supply specifications of the inverter.
Must be selected carefully since an inrush current flows in the inverter at
power ON.
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 (500 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.
Install this to reduce the electromagnetic noise generated from the inverter.
The noise filter is effective in the range from about 0.5 to 5 MHz. A wire
should be wound four turns at maximum.
Suppresses the power supply harmonics significantly. Install this as
required.
Provides a large braking capability. Install this as required.
Install this to reduce the radio noise.
Allows the inverter to provide the optimal regenerative braking capability.
Install this as required.
Install this to reduce the electromagnetic noise generated from the inverter.
The noise filter is effective in the range from about 0.5 to 5 MHz. A wire
should be wound four turns at maximum.
Connect a squirrel-cage induction motor.
