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