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(CE101,CE102,CE103) assembled in accordance the specification? (Outdoor PBA)
5) Is the DC link resistor(R104,R106,R107,R108) value is normal? (Outdoor PBA)
5) Is the DC_link resistor(R104,R106,R107,R108) value is normal? (Outdoor PBA)
