Pictures Name Descriptions
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.
C.3 Power supply
Please see Installation guidelines.

Check that the voltage degree of the VFD complies with the voltage of the
supply power voltage.
C.4 Cables
C.4.1 Power cables
Dimension the input power and motor cables according to local regulations.

The input power and the motor cables must be able to carry the corresponding load currents.

The cable must be rated for at least 70 °C maximum permissible temperature of the conductor in
continuous use.

The conductivity of the PE conductor must be equal to that of the phase conductor (same
cross-sectional area). For the 030G/037P and higher models, the cross sectional area of the PE
grounding conductor can be slightly less than the recommended area.
