4.2 Power Supply
4.2.1 Mainboard Power Supply
The power supply of the ADLE3800HDC is realized via a 2x2pin connector (P20THR-1787014). The main
24V power lines are assigned to pin 3.
If a UPS is present you need to have a possibility to shut down the board in a regular way without
activating the UPS, thereby preventing premature aging of UPS components. That's what pin 1
(PC_START) is for. When pulled high (24V) a regular shutdown without UPS activity is triggered. As a
part of this regular shutdown pin 2 (PC_AKTIV) is pulled from 24V to 0V.
