Hello. I have a problem with the MPPU1 cabinet, in the board A4 A1 (AC supply board) the LED DE2 is always on, the manual says: Fault on +- 300 VDC,I checked all the board and all are ok. I don't know if the problem is with the security board because it don't send the signal "MAINS ON" to the board A4 A1.
The control put code error 4246.
Check the large fuses F11/12 on the front of the A4A1 module, top is the -300vdc, bottom +300vdc. The A4A1 takes 380vac and generates plus/minus 300vdc for the inverters. F4 and F10 are for phase 2 and phase 3. N1-N4 indicate line power input. line power comes in through X8 then to CR6,7,8 to R1 and R14 indicated by N5 at R11, R12. 600vdc across R13, or +300vdc across R3 and -300vdc across R4. After R3/4 it goes into the capacitor bank and then to the F11/12 fuses.
