Check and correct circuit cables. Check IPDU. [. . . ] By doing so, the power consumption can be decreased because the breaker can be turned off if there is no possibility of freezing of the base in cooling operation, etc. When the cord heater power is connected to the inverter P board assembly or others without connected to the . C. exclusive breaker, the control P board of the inverter assembly may cause a failure. 1 1-2 Photo / Explanatory diagram Procedure Remove each cabinet, inverter assembly, motor base assembly, and partition board assembly.
