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. Connect the optional radio noise filter FR-BIF (for use in
the input side only), line noise filter FR-BSF01/FR-BLF, Filterpack, or EMC filter to minimize interference.
• 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.
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 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 suppress harmonics and to improve the power factor.
Select a reactor according to the applied motor capacity.
When using a DC reactor, remove the jumper across terminals P/+ and P1
before connecting a DC reactor to the inverter.
Install this to reduce the electromagnetic noise generated from the inverter.
Install this to reduce the radio noise.
Connect between the inverter and a personal computer with a USB (ver.
1.1) cable.
Increases the braking capability.
Install this to reduce the electromagnetic noise generated from the inverter.
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).
An IPM motor cannot be driven by the commercial power supply.
