For LG elevators using the INV-SDC or INV-SDCL, if an electronic arrival indicator is being used on site with a voltage of 24VDC, the diode connecting D13 and D14 on the board needs to be disconnected. If a mechanical arrival indicator is used on site with a voltage of 48VDC, then the diode D13 and D14 on the board should be connected and not disconnected.
