ఐ During "Discharge mode of DC link voltage", voltage of INV1 and INV2 will be displayed alternately.
ఐ E v en when the outdoor unit power is off, it is dangerous when you come in contact with inverter PCB and fan PCB since they are
charged with high DC voltage.
ఐ When replacing/repairing the PCB, cut-off the power and wait until the DC voltage is discharged before replacing/ repairing them.
(Wait for more than 15 minutes to allow it to discharge naturally. )
ఐ W hen there were error, 'Dicharge mode of DC link voltage' may not have been effective Especialy if error E464 and E364 have been
occured, power element might be damaged by fire and therefore, do not use the 'Discharge mode of DC link voltage'.
