DANGER 

Potential equalization in high-voltage system. 

Mortal hazard if the potential equalization screw connection is not correct! 

• Observe the safety requirements for the potential equalization screw connection.
• Clean contact faces and have then checked by a second person.
• Tighten the screws/nuts for potential equalization with torque; have a second person check the torque.
• Correct execution of these tasks must be documented in the vehicle records by both persons.
