61 00... Notes on earth bonding screw connections

Connecting high-voltage components to body ground is crucial to safety for reasons of equipotential bonding. For this reason, it is prohibited to operate any high-voltage components without them being correctly connected to body ground.

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 earth 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.
• Both persons must document that the work has been carried out correctly in the vehicle records.
