    Rev.01 Issue 09/05 7 Mechanical assembly and set-up CAUTION The safe operation of the lift door drive requires that it is correctly installed and put into operation by qualified personnel under consideration of the warning references in these operating instructions. Before working on the door drive you must ensure that voltage has been removed from the controller.

  • Page 14: Electrical Set-up And Initial Start-up

    Rev.01 Issue 09/05 8 Electrical set-up and initial start-up WARNING With the operation of electrical equipment inevitably some parts of the equipment contain dangerous voltage. Neglecting the operating instructions can therefore lead to severe bodily injuries or property damage. Therefore the warnings must be absolutely followed. During the start-up of the controller (in particular during automatic parameter determination) the door movements cannot always be externally influenced.
