Setting outdoor unit option switch and key function
❋ During "Discharge mode of DC link voltage", voltage of INV1 and INV2 will be displayed alternately.
❋ Even 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.
❋ 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 and E364
have been occured, power element might be damaged by fire and therefore, do not use the 'Discharge mode of DC link
voltage' .
