2.5 Inverter PCB replacement procedure
(Note) If cut the tie, the wiring cables should be bound with new tie again.
Exchange the inverter PCB according to the following procedure.
①
Replace the inverter PCB after elapsing 3 minutes from power OFF.
(Be sure to measure voltage (DC) of two places (1. Power source for PCB 2. Power source for fan motor) and check
that the voltage is discharged completely. (Refer to Fig.1))
②
Disconnect all of terminals and connectors from the inverter PCB before replace the invertor PCB.
③
Replace to the new PCB.
④
Set the setting switches (JSW 10, 11) of new PCB as shown in table 1.
⑤
Connect all of terminals and connectors to the new PCB securely.
(Check the secure connection of terminals and connectors again)

●
Securely replace PCB according to this following instruction.
If PCB is incorrectly replace, it will cause an electric shock or fire.
Be sure to check that the power source for the outdoor unit is turned OFF before replace PCB,
The PCB replacement under current-carrying will cause an electric shock.
After finishing PCB replacement, check that wiring is correctly connected with the PCB before power
distribution, If PCB is incorrectly replace, it will cause an electric shock or fire.
CAUTION
Bundle the wiring so as not to tense because it will cause an electric shock.
