WARNING
Danger of injury from electric shock!
Power supply lines run in the suspension arm system and the M6 service head. Touching live
parts can cause life-threatening electric shock.

In order to avoid the risk of electric shock, the suspension arm system may be connected
only to a supply network with a protective conductor in such a way that all of its phases
can be simultaneously disconnected from the mains.
Disconnect the suspension arm system from the mains before beginning any maintenance
work.
•
Disconnect all phases of the customer-side power supply and secure it against
reactivation.
•
Ensure that all the devices connected to the M6 service head are de-energized.
