Cables
Device to transfer the electronic signals
Breaker
Prevent from electric shock and protect the power supply
and the cables system from overcurrent when short circuits
occur. (Please select the breaker with the function of
reducing high order harmonic and the rated sensitive
current to 1 VFD should be above 30mA).
Input
reactor
This device is used to improve the power factor of the input
side of the VFD and control the higher harmonic current.
The 037G/045P and higher models can be connected with
DC reactor.
DC reactor
Input filter
Control the electromagnetic interference generated from
the VFD, please install close to the input terminal side of
the VFD.
or
Braking
unit or
resistors
Shorten the DEC time
The 030G/037P and lower models only need braking
resistors and the 037G/045P and higher models need
braking units
Output
filter
Control the interference from the output side of the VFD
and please install close to the output terminals of the VFD.
Output
reactor
Prolong the effective transmitting distance of the VFD to
control the sudden high voltage when switching on/off the
IGBT of the VFD.
