CAUTION
• Do not fit capacitive equipment such as power factor correction capacitor, radio noise filter or surge suppressor to the
output side of the inverter. This will cause the inverter to trip or power factor correction capacitor and surge suppressor to
be damaged. If any of the above devices are connected, immediately remove them. (If the radio noise filter is connected,
switching power off during motor operation may result in "E.UVT". In this case, connect the radio noise filter on the pri-
mary side of the magnetic contactor.)
• Electromagnetic wave interference
The input/output (main circuit) of the inverter includes harmonic components, which may interfere with the communica-
tion devices (such as AM radios) used near the inverter. In this case, install the radio noise filter (for use on the input side
only) or line noise filter to minimize interference.
• For details of peripheral devices, refer to manuals of each peripheral devices.
Power supply
Use within the permissible power supply specifications of the inverter. (Refer to page 220.)
No-fuse breaker (NFB) or earth leakage circuit breaker (ELB)
The breaker must be selected carefully since an in-rush current flows in the inverter at power-on.
(Refer to page 3.)
Magnetic contactor
Install the magnetic contactor to ensure safety. (For details, refer to page 21.)
Do not use this magnetic contactor to start and stop the inverter. Doing so will cause the inverter
life to be shorten. (Refer to page 3.)
Power factor improvement reactor
The reactors must be used when the power factor is to be improved or the inverter is installed near
a large power supply system (1000kVA or more and wiring distance within 10m
inverter may be damaged if you do not use reactors.
Make selection carefully.
• DC reactor, AC reactor
(Caution) Remove the jumpers across terminals P-P1 to connect to the DC reactor.
Noise filter
Install a noise filter to reduce the magnetic noise generated from the inverter.
• Line noise filter
Effective in the range from about 1MHz to 10MHz. When more wires are passed through, a
more effective result can be obtained. (Note that the number of wires run through is limited when
fitting to the output side.)
• Radio noise filter
Effective in reducing the noises in the AM radio frequency band. Dedicated filter for the input side.
Inverter
The life of the inverter is influenced by ambient temperature. The ambient temperature should
be as low as possible within the permissible range. This must be noted especially when the
inverter is installed in an enclosure. (Refer to
Wrong wiring might lead to damage of the inverter. The control signal lines must be kept fully
away from the main circuit to protect them from noise. (Refer to page 4.)

Motor with encoder
Perform offline auto tuning when exercising vector control with encoder. (Refer to page 132.)
Devices connected to the output
Do not install a power factor correction capacitor, surge suppressor or radio noise filter on the
output side of the inverter.
When installing a no fuse breaker on the output side of the inverter, contact each manufacturer for
selection of the no fuse breaker.
Ground
To prevent an electric shock, always ground the motor and inverter. For reduction of induction
noise from the power line of the inverter, it is recommended to wire the ground cable by returning it
to the ground terminal of the inverter.
