Current cut is indicated and the compressor cannot operate
Notes (1) when a short-circuit or ground-fault occurs in the
compressor motor, the current cut function is also
activated.
If the insulation resistance is 10MΩ or more, it is
normal.
The insulation resistance may considerably drop
depending on the refrigerant volume in the
compressor, but this is not faulty.
