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
YES
YES
YES
