(ii) Micro inverter series
1) Model FDC100VN, 125VN, 140VN
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
check that the
voltage is discharged sufficiently
.(Refer to Fig.1))
b)
Take off the connection of inverter PCB terminal block connector and remove the screw of power transistor then

don’t use soldering in the connection.Tighten properly the power transistor with a screw and make sure there is no
clearance gap.Power transistor can be damage if not properly tighten.(Recommended power transistor tightening
torque:0.98~1.47N·m)
