Diameter 171.1 mm
Figure 12: Example of a Simple Mounting Bracket
Instead of drilling individual holes in a circular arc with a diameter of 171.1 mm with 4.5 mm diameter pairs of
holes opposite each other, you can also cut two arc-shaped slits in the plate.This requires a cutting device but
has the advantage that the ILM can be aligned continuously and therefore more accurately on the vertical axis
during operation.
