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 VFDs of 220V (18.5
–55kW), 460V
(G-type
≥37kW, P-type≥45kW) and 575V have
external DC reactors.
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 VFD
s of 220V (≤15kW) and 460V
(G-
type≤30kW, P-type≤37kW) need braking
resistors and the VFDs of 220V (18.5
–55kW),
460V (G-type
≥37kW, P-type≥45kW) and 575V
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.
D.3 Power supply
Please refer to
Electrical Installation
.
Check that the voltage degree of the VFD complies with the voltage of the
supply power voltage.
D.4 Cables
D.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.
