Even when the outdoor unit power is off, it is dangerous when you come in contact with inverter PCB since it is charged
with high DC voltage.
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.)
When there were error, 'Dicharge mode of DC link voltage' may not have been effective. Especialy if error E464 has been
occured, power element might be damaged by re and therefore, do not use the 'Discharge mode of DC link voltage'.
During "Discharge mode of DC link voltage", voltage of INV will be displayed.
