Inverter And Peripheral Devices - Mitsubishi F700 Series 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 366)
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 shorten.
(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 01160 or less, 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 13.)
· Refer to the Instruction Manual of each option and peripheral devices for details of peripheral devices.
