The risk analysis should take into consideration all danger zones for the automation device, which should be appropriately
protected and marked.
In a clearly visible area, apply a sign with information identifying the motorised door or gate.
The installer should provide the user with all the information relating to automatic operation, emergency opening and
maintenance of the motorised door or gate.
