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.
