OUTLINE
1.2 Inverter and peripheral devices
CAUTION
· Do not install a power factor correction capacitor, surge suppressor or capacitor type filter 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, set the EMC filter valid to minimize interference.
(Refer topage 15.)
· Refer to the Instruction Manual of each option and peripheral devices for details of peripheral devices.

Devices connected to the output
Use within the permissible power supply
specifications of the inverter.
The regeneration braking
capability of the inverter can be
exhibited fully.
Install this as required.
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 shorten.
The inverter can be connected
with a computer such as a
programmable controller and
with GOT (human machine
interface).
It supports Mitsubishi inverter
protocol, Modbus-RTU (binary)
protocol and BACnet MS/TP
protocol.
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.
Power supply harmonics
can be greatly suppressed.
Install this as required.
Greater braking capability
is obtained.
Install this as required.
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 0.5MHz to 5MHz.
A wire should be wound four
turns at a maximum.
: Install these options as required.

Ground
To prevent an electric shock, always ground the
motor and inverter.
For the FR-F720-03160 (FR-
F740-01800) or more, a DC
reactor is supplied.
Always install the reactor.
*1 Compatible with the FR-F720-02330 (FR-F740-01160) or less.
*2 Compatible with the FR-F720-03160 (FR-F740-01800) or more.
Reactor (FR-HAL, FR-HEL)
Install reactors 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 (1000kVA or more).
The inverter may be damaged if you do not use
reactors.
Select the reactor according to the model.
For the FR-F720-02330 (FR-F740-01160) or less,
remove the jumpers across terminals P/+ and P1 to
connect to the DC reactor.
EMC filter
(ferrite core)
(FR-BLF)
The FR-F720-02330
(FR-F740-01160) or
less has a built-in
common mode choke.

Inverter
(FR-F700)
The life of the inverter is influenced by 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. (Refer to page 10)
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 14)
Refer to page 15 for the built-in EMC filter.
