Installation And Wiring - Mitsubishi Electric F700 Instruction Manual

2 INSTALLATION AND WIRING

Three-phase AC power supply
Use within the permissible power supply
specifications of the inverter.
(Refer to page 116)
Moulded case circuit
breaker (MCCB)
or earth leakage current
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.
For the 01160 or less, remove the jumpers across
terminals P/+-P1 to connect to the DC reactor.
(Refer to the Instruction Manual (applied).)

*2 Compatible with the 01800 or more.
CAUTION
· Do not install a power factor correction capacitor, surge suppressor or radio noise 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 to Instruction Manual (applied).)
· Refer to the instruction manual of each option and peripheral devices for details of peripheral devices.

For the 01800 or more, a
DC reactor is supplied.
Always install the reactor.

Inverter
PLC
(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)

Noise filter
(FR-BSF01, FR-BLF)
Install a noise filter to reduce

generated from the inverter.
Effective in the range from
about 1MHz to 10MHz.
A wire should be wound four
turns at a maximum.

Devices connected to the output
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.
Earth
To prevent an electric shock, always earth the
motor and inverter.
