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 inverter should be above 30mA).
Input reactor
This device is used to improve the power factor
of the input side of the inverter and control the
higher harmonic current.
Input filter
Control the electromagnetic interference
generated from the inverter, please install close
to the input terminal side of the inverter.
Braking resistors
Shorten the DEC time.
Only braking resistors are needed for Goodrive20
inverters.
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.
Membrane of heat
releasing holes at the side
Apply to severe environment and improve
protective effect.
Derate 10% of the machine.
C.2 Power supply
Check that the voltage degree of the inverter complies with the voltage of the
supply power voltage.
C.3 Cables
C.3.1 Power cables
Dimension the input power and motor cables according to local regulations.
Note: A separate PE conductor is required if the conductivity of the cable shield is not sufficient for the
purpose.
C.3.2 Control cables
All analog control cables and the cable used for the frequency input must be shielded.
The relay cable needs the cable type with braided metallic screen.
Note: Run analog and digital signals in separate cables.
