Power
supply
Please follow the specific
power supply requirement
shown in this manual.
Fuse/NFB
There may be an inrush
current during power up.
Please refer to 3.7.1 and
select the correct fuse /NFB.
Magnetic
contactor
Please do not use a Magnetic
contactor as the I/O switch of
the inverter, as it will reduce
the operating life cycle of the
inverter.
Input AC
Line Reactor
AC line reactor should be
installed to improve the input
power factor. The wiring
distance should be less than
10m. Please refer to 3.7.6.
Zero-phase
Reactor
Zero-phase reactors are used
to reduce radio noise especially
when audio equipment installed
near the inverter. Effective for
noise reduction on both the
input and output sides. The
frequency band effective range
is from 1MHz to 10 MHz.
Please refer to 3.7.5.
EMI filter
Used to reduce
electromagnetic interference.
Braking unit
Used to reduce stopping time
of the motor.
Output AC
Line Reactor
Motor surge voltage
amplitudes depending on
motor cable length. The output
AC line reactor is necessary to
install on the inverter output
side. Please refer to 3.7.6.
