❋
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 there were error, ‘Discharge mode of DC link voltage’ may not have been effective. Especially if error E464 and E364
have been occurred, power element might be damaged by fire and therefore, do not use the ‘Discharge mode of DC link
voltage’.
