❇
Even when the outdoor unit power is o , 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-o 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 e ective. 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.
