WARNING:
Potential equalization in high-voltage system.
Mortal hazard if the potential equalization screw connection is not correct!
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.
WARNING:
Hot fluids.
