Inverter And Peripheral Devices - Mitsubishi FR-F720-00046-NA Instruction Manual

1.2 Inverter and peripheral devices

Three-phase AC power supply
Use within the permissible power supply
specifications of the inverter.
(Refer to page 370)
Moulded case circuit
breaker (MCCB)
or earth leakage circuit
breaker (ELB), fuse
The breaker must be selected carefully since
an in-rush current flows in the inverter at
power ON.
(Refer to page 4)
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.
(Refer to page 4)
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 lower,
remove the jumpers across terminals P/+ and P1 to
connect to the DC reactor.

: Install these options as required.
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.

Inverter
(FR-F700)
The life of the inverter is influenced by surrounding air
RS-485 terminal block
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.

Noise filter
(ferrite core)
(FR-BSF01, FR-BLF)
Install a noise filter (ferrite
core) to reduce the
electromagnetic noise
generated from the inverter.

about 0.5MHz to 5MHz.
A wire should be wound four
turns at a maximum.
