Information
Handling high-voltage lines:
- Do not support yourself or your tools on high-voltage lines and their components.
- Work involving metal-removing, deforming and sharp-edged tools close to high-voltage components and lines is prohibited.
- Work involving heat sources such as welding, soldering, hot air and thermal bonding close to high-voltage components and lines is prohibited.
- High-voltage lines must not be extensively bent or kinked.
- Perform a visual inspection of the high-voltage connectors before installing the high-voltage lines.
- If you have questions or if you are unclear about anything, consult the relevant high voltage expert or your importer.
Information
Mark the spacer sleeves for the cover of the high-voltage battery before removal and note the installation position. The spacer sleeves have different sizes (heights) and must not be interchanged.
- Read the warning notices.
