Inverter and peripheral devices

(FR-BAL-B)
High power factor
converter
(FR-HC
Power supply harmonics can
be greatly suppressed.
Install this as required.
Reactor (FR-BAL-B, FFR-HEL-(H)-E)
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. For the 01160 or less, remove the jumpers
across terminals P/+ and P1 to connect to the DC reactor. (Refer to section 3.7.6.)
For the 01160 or less: FFR-HEL-(H)-E
For the 01800 or more, a DC reactor is supplied. Always install the reactor.

FR-F700 EC
3-phase AC power supply
Use within the permissible power
supply specifications of the inverter.
(Refer to Appendix A.)
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 section 3.1.1.)
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 section 3.1.1.)
AC reactor
DC reactor
(FFR-HEL-(H)-E)
EMC filter
(FFR-CS / FFR-MSH)
(optional)
Install this as required.
Power regeneration

Greater braking capability
is obtained.
Install this as required.
PLC
RS485 terminal block
The inverter can be connected
with a computer such as a PLC
and with GOT (Human Machine
Interface– HMI). It supports
Mitsubishi inverter protocol,
Modbus-RTU (binary) protocol
and BACnet MS/TP protocol.

The regenerative braking
capability of the inverter can
be exhibited fully.

Install this as required.
Inverter and peripheral devices
HMI
Inverter (FR-F700 EC)
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 section 2.4.2.)
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 section 3.2.)
Refer to section 3.8.3 for the built-
in EMC filter.
Output filter
Earth
(optional)
Earth
Devices connected to the output
Do not install a power factor correction capacitor,
surge suppressor, arrester 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.
Earth
To prevent an electric shock, always earth the
motor and inverter.
