BMW 3: Connections
The connections at the Electrical Machine Electronics can be divided into four categories:
- Low-voltage connections
- High-voltage connections
- Connection for potential compensation line
- Connections for coolant lines.

High-voltage connections
At the Electrical Machine Electronics, there is a total of three high-voltage
connections to connect the
lines for other high-voltage components. The connections for the electric A/C

High-voltage cables
The high-voltage cables connect the high-voltage components and are
identified by orange cable
sleeves. The manufacturers of hybrid cars have agreed on a uniform
identification of the high-voltage
