2 INSTALLATION AND WIRING
CAUTION
· Do not install a power factor correction capacitor or surge suppressor 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 to the Instruction Manual (applied).)
· 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 regenerative 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 computers
such as PLC.
It supports Mitsubishi inverter
protocol and Modbus-RTU
(binary) protocol.
Do not install a power factor correction capacitor,
surge suppressor or radio noise filter 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 a noise filter 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.
Reactor (FR-HAL, FR-HEL)
Reactors (option) should 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 (1000kVA 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/+-P1 to
connect to the DC reactor.

I
nverter
(FR-F700)
The life of the inverter is influenced by ambient
temperature. The ambient temperature should be as low
as possible within the permissible range. Especially when
mounting the inverter inside an enclosure, take cautions
of the ambient temperature.
(Refer to page 6)
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.
