Connection Example - Mitsubishi Electric FR-F700PJ Series Manual

Connection Example

AC power supply
Use within the permissible power supply
specifications of the inverter. To ensure
safety, use a moulded case circuit breaker,
earth leakage circuit breaker or magnetic
contactor to switch power ON/OFF.
(Refer to page 11)
Molded case circuit breaker (MCCB),
earth leakage circuit breaker (ELB),
or fuse
The breaker must be selected carefully
since an inrush current flows in the
inverter at power on.
(Refer to page 68)
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.

Noise filter (ferrite core)∗
(FR-BSF01, FR-BLF)
(Refer to page 62)
* Not necessary if Filterpack (FR-BFP2) is used.

NOTE
 The life of the inverter is influenced by surrounding air temperature. Use the product within the permissible
surrounding air temperature. This must be noted especially when the inverter is installed in an enclosure.
(Refer to chapter 1 of
 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 17)
 Do not install a power factor correction capacitor, surge suppressor or noise filter (capacitor) 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, install the FR-BIF optional EMC filter
(capacitor) (for use in the input side only) or FR-BSF01 or FR-BLF noise filter (ferrite core) to minimize interference.
(Refer to chapter 3 of
 Refer to the Instruction Manual of each option and peripheral devices for details of peripheral devices.
 An IPM motor cannot be driven by the commercial power supply.
 An IPM motor is a motor with permanent magnets embedded inside. High voltage is generated at the motor terminals while the
motor is running. Before closing the contactor at the output side, make sure that the inverter power is ON and the motor is stopped.

contact each manufacturer for selection of the

Earth (Ground)
To prevent an electric shock, always earth (ground)
the motor and inverter. For reduction of induction noise
from the power line of the inverter, it is recommended
to wire the earth (ground) cable by returning it to the
earth (ground) terminal of the inverter.
RS-232C - RS-485 converter is
required when connecting to PC
with RS-232C interface.
