Index Explanation
1 Connection�for�proximity�line
2 Connection�for�phase�L1
3 Connection�for�protective�earth�(PE)
4 Connection�for�neutral�conductor�(N)
5 Connection�for�pilot�line
6 Protective�cap�for�AC�charging�socket
7 Protective�cap�for�DC�charging�socket
8 Connection�for�DC�ground�cable
9 Connection�for�DC�positive�wire
The�high-voltage�cables�of�the�charging�socket�are�connected�to�the�electrical�machine�electronics
(via�the�KLE�in�the�US�market).�Phase L1�and�neutral�conductor N�are�designed�as�shielded�high-
voltage�cables�and�end�with�a�flat�high-voltage�connector�at�the�alternating�current�connection�of�the
electrical�machine�electronics.�The�pilot�line�and�the�proximity�line�are�simple�signal�lines.�These�signal
lines�are�also�shielded�and�end�at�a�connector�in�the�charging�interface�module�(LIM).�The�protective
earth�is�connected�electrically�to�ground�in�close�proximity�to�the�charging�socket.�This�ensures�proper
grounding.
A�C-shaped�fiber-optic�conductor�runs�around�the�charging�socket�at�the�vehicle.�With�this�C-shaped
fiber-optic�conductor�it�is�possible�to�show�the�status�for�charging.�The�lighting�of�the�fiber-optic
conductor�is�effected�using�two�LEDs�which�are�controlled�by�the�LIM.
The�charging�socket�at�the�vehicle�can�only�be�replaced�together�with�the�high-voltage�cable�as�one
unit.
6.2.5.�Charging�interface�module�(LIM)
The�LIM�enables�communication�between�the�vehicle�and�charging�station.�The�voltage�supply�of�the
LIM�control�unit�is�effected�by�terminal�30F.�There�is�a�terminating�resistor�for�the�PT-CAN�in�the�LIM.
The�LIM�can�also�wake�up�the�control�units�in�the�vehicle�electrical�system�when�the�charging�cable�is
connected.�There�is�also�a�line�which�runs�directly�from�the�LIM�control�unit�to�the�electrical�machine
electronics.�Only�when�the�LIM�control�unit�enables�the�charging�procedure�via�a�signal�on�this�line,
does�the�electrical�machine�electronics�start�the�voltage�conversion�and�thus�the�charging�procedure.
