Samsung AM060MXMDCH Series - Key Operation Modes; K3 and K4 Operation Functions

ENGLISH
❋
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-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, 'Discharge mode of DC link voltage' may not have been eective. Especially if error E464 has
been occurred, 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.
