Input reactor
This device is used to improve the power
factor of the input side of the inverter and
control the higher harmonic current.
The inverter above 37kW (including 37kW)
can be connected with DC reactor.
DC reactor
Input filter
Control the electromagnetic interference
generated from the inverter, please install
close to the input terminal side of the
inverter.
or
Braking unit or resistors
Shorten the DEC time
The inverters below 30kW(including 30kW)
only need braking resistors and the
inverters above 37kW(including 37 kW)
need braking units
Output filter
Control the interference from the output
side of the inverter and please install close
to the output terminals of the inverter.
Output reactor
Prolong the effective transmitting distance
of the inverter to control the sudden high
voltage when switching on/off the IGBT of
the inverter.
C.3 Power supply
Please refer to Electronical Installation.
Check that the voltage degree of the inverter 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).
• Refer to chapter Technical Data for the EMC requirements.
A symmetrical shielded motor cable (see the figure below) must be used to meet the EMC
requirements of the CE.
A four-conductor system is allowed for input cabling, but a shielded symmetrical cable is
