Low-voltage￿connections
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
