a) Replace the PCB after elapsing 3 minutes from power OFF.
(Be sure to measure voltage (DC) on both capacitor terminals located in controller back , and
voltage is discharged sufficiently.(Refer to Fig.1))
b) Tak e off the connection of inv e rter PCB terminal block connector and remov e the screw of power transistor then
c) Refer to table1 for the setting of switch (JSW10 , 11) of new PCB.
