• Check compressor error.
• Check power voltage. (AC380–10%, 415V +10%).
• Check cable of compressor and phase-missing.
• Check connector/terminal connection on IPDU P.C. board.
• Check conduction of case heater.
(Check activation error due to liquid stagnation in compressor.)
• Check outdoor P.C. board (IPDU) error.
• Check outdoor MG-SW or OCR.

it mentions theres a sub code to tell ya if its comp1 or 2- if its lost a phase then inv pcb should be protected, check correct power to outdoor- water in isolator,loose connections on circuit breakers
