Inverter Error
YES
NO
OK
Check Point 1-2 : Noise, momentary open, voltage drop
Inverter PCB Error information received from Inverter PCB
1. Noise, momentary open, voltage drop. 2. Power supply to Filter PCB (INV) to Inverter PCB
wiring disconnection, open 3. Filter PCB ( INV) defective 4. Inverter PCB defective
Check if temporary voltage drop was not generated.
Check if momentary open was not generated.
Check if ground is connection correctly or there are no related cables near the
power line.
Check Point 2 : Check the wiring (Power supply to Filter PCB (INV) to Inverter PCB)
Connector and wiring connection state check
Cable open check
Check resistance of cement resistor
Check Point 1-1 : Turn the power
on again.
Error displayed again?
Check Point 3 : Check Cement resistor
