Inverter and peripheral devices
1.2 Inverter and peripheral devices
NOTE
 The life of the inverter is influenced by surrounding air temperature. Use the product within the permissible surrounding
air temperature. This must be noted especially when the inverter is installed in an enclosure.
(Refer to page 9)
 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 18)

Do not install a power factor correction capacitor, surge suppressor or EMC filter (capacitor) on the inverter output
side. This will cause the inverter to trip or the capacitor and surge suppressor to be damaged. If any of the above
devices are connected, immediately remove them.

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, install the FR-BIF optional EMC filter
(capacitor) (for use in the input side only) or FR-BSF01 or FR-BLF EMC filter (ferrite core) to minimize interference.
(Refer to page 45).
 Refer to the Instruction Manual of each option and peripheral devices for details of peripheral devices.

An IPM motor cannot be driven by the commercial power supply.
 An IPM 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.
AC power supply
Use within the permissible power supply
specifications of the inverter. To ensure
safety, use a moulded case circuit breaker,
earth leakage circuit breaker or magnetic
contactor to switch power ON/OFF.
Magnetic contactor (MC)
Install the magnetic contactor to ensure
safety. Do not use this magnetic contactor
to start and stop the inverter. Doing so will
cause the inverter life to be shortened.
EMC filter
(ferrite core)
(FR-BSF01,
FR-BLF)
Install an EMC filter
(ferrite core) to reduce
the electromagnetic
noise generated from
the inverter.Effective
in the range from
about 0.5MHz to 5MHz.
A wire should be
wound four turns at a
maximum.
Devices connected
to the output
Do not install a power
factor correction capacitor,
surge suppressor or EMC filter (capacitor) on the output
side of the inverter. When installing a moulded case
circuit breaker on the output side of the inverter,
contact each manufacturer for selection of the
moulded case circuit breaker.
The regenerative braking capability
of the inverter can be exhibited fully.
Install this as required. Power supply harmonics
can be greatly suppressed.
Install this as required.

Reactor (FR-HAL, FR-HEL option)
Reactors (option) must be used when
power harmonics measures are taken,
the power factor is to be improved or the
inverter is installed near a large power
supply system (500kVA or more). The
inverter may be damaged if you do not
use reactors. Select the reactor according
to the model. Remove the jumpers across
terminals P/+ and P1 to connect the DC reactor.
EMC filter (ferrite core) *
(FR-BSF01, FR-BLF)
Moulded case circuit breaker
(MCCB), earth leakage circuit
breaker (ELB), or fuse
The breaker must be selected carefully
since an in-rush current flows in the
inverter at power on.
Install an EMC filter (ferrite core)
to reduce the electromagnetic
noise generated from the
inverter. Effective in the range
from about 1MHz to 10MHz.
When more wires are passed
through, a more effective result
can be obtained. A wire should
be wound four turns or more.
* Not necessary if Filterpack (FR-BFP2) is used.
Earth (Ground)
To prevent an electric shock, always earth (ground)
the motor and inverter. For reduction of induction noise
from the power line of the inverter, it is recommended
to wire the earth (ground) cable by returning it to the
earth (ground) terminal of the inverter.
