The power supply of the DME is structured as follows:
Terminal 15 WUP is signalled to the DME directly via a separate pin.
In response, the DME activates the DME main relay. The DME main relay supplies other inputs of the DME with voltage.
For storage applications, the DME has a sustained power supply via terminal 30.
The earth (ground) connection of the DME is ensured by a pin.
The functions of power management are implemented using the IBS. The DME is connected via the BSD bus to the IBS.
