Installation And Wiring - Mitsubishi Electric FR-F700 Series Instruction Manual

2 INSTALLATION AND WIRING

Three-phase AC power supply
Use within the permissible power supply
specifications of the inverter.
(Refer to page 90)
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 3)
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 shorten.
(Refer to page 3)
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.
(Refer to the Instruction Manual (applied).)

*2 Compatible with the FR-F740-01800 or more.
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.

Inverter
(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
The inverter can be control signal lines must be kept fully away from the main
circuit to protect them from noise.(Refer to page 8)

To prevent an electric shock, always ground the
motor and inverter.
