1. Checklist :
1) Is the input voltage of outdoor terminal block is normal?
2) Is the input voltage is higher than 300Vac?
3) Is the reactor wire connected?
4) Is the DC_link capacitor(A") assembled in accordance the specification? (Outdoor PBA)
5) Is the DC_link resistor("B") value is normal? (Outdoor PBA)
6) Is the PFC resistor("C") value is normal? (Outdoor PBA)
2. Troubleshooting procedure
Is the connected of reactor wire?
Is the the input voltage is nomal?
Normal range(180Vac 270Vac)
Start the operation (cooling mode or heating mode)
("A") is normal in operation mode?
Normal range(280Vdc 320Vdc)
