NOTICE
The frame is not in scope of delivery. Installation is carried out according to the design of the frame.
• Use screws with a minimum strength class of 8.8.
When using the elongated holes

, the bearing surface of the screws is too small.
• Use screws with the enclosed washers.
The parallel kinematic system must be fastened to a frame only in the area of the corner bracket of the
mounting frame. A flat bearing surface that is resistant to torsion is essential in the area of the corner
brackets. In order for the parallel kinematic system to attain the positioning accuracy described in the
technical data, the following minimum requirements apply to the bearing surfaces:
–
Evenness = 0.05 mm
–
Parallelism = 0.5 mm.
Other holes can be used only as an assembly aid or for mounting additional installation elements,
such as cable guide.
