Samsung AM***XMDCH Series Installation Manual page 43

❋ 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, 'Discharge mode of DC link voltage' may not have been effective. Especially if error E464 has
been occurred, power element might be damaged by fire 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.
