Diagram 3-2 The main circuit diagram (≥37kW) 
Note: 
1.  The  inverter  above  37kW  (including  37kW)  supports  external  DC  reactor  which  is  an 
optional part. Before connecting, it is necessary to remove the copper row between P1 and
(+). 
2. The inverter below 30kW (including 30kW) supports external braking resistor; the inverter 
above 37kW (including 37kW) supports external braking units. Both the braking unit and the 
braking resistor are optional parts.
