Check Point 1 : Check the magnetic relay (for invertert) coil side wiring
Connector and wiring connection state check
Cable open check
Cable open check
Check Point 2 : Check Power supply to Filter PCB (INV) to inverter PCB wiring
Connector and wiring connection state check
Chec Point 3-1 : Magnetic relay activation circuit
Chack the DC Voltage (12V) of CN808 on INVERTER PCB
>>
Check Point 4 : Main PCB output 230 V for Magnetic relay
Check the AC230V of CN130 on Main PCB
