Notes on earth bonding screw connections

Connecting high-voltage components to GND is crucial to safety for reasons of potential equalization. For this reason, it is prohibited to operate any high-voltage components without them being correctly connected to GND.

For a correct ground connection, the retaining elements of high-voltage components must not be painted. Follow further painting notes.

Potential compensation wires, high-voltage cables and the battery ground lead of the electrical machine electronics have a safety screw connection. The following procedure must be adopted without fail:

• Clean contact faces and have then checked by a second person.
• Tighten down screws/bolts to specified torque.
• Have tightening torque checked by a second person.
• Correct execution of these tasks must be documented in the vehicle records by both persons.
