In�the�multipolar�low-voltage�connector�at�the�electrical�machine�electronics,�which�is�visible�from�the
outside,�the�following�lines�and�signals�are�combined:
• Voltage�supply�for�the�EME�control�unit�(terminal�30B�from�the�power�distribution�box�at�the
front�and�ground)
• Terminal 30C�from�the�safety�battery�terminal�(is�evaluated�by�the�EME�control�unit�in�order�to
identify�an�accident)
• Bus�system�PT-CAN2�(In�the�EME�control�unit�there�is�a�terminating�resistor�with�120 Ω�for
the�PT-CAN2)
• Wake-up�line
• Control�line�for�the�convenience�charging�electronics�to�enable�the�charging�procedure
• Input�and�output�of�the�circuit�of�the�high-voltage�interlock�loop�(EME�control�unit�evaluates
the�signal�and�initiates�a�shutdown�of�the�high-voltage�system�in�the�event�of�an�open�circuit�of
the�circuit)
