Note:• Make sure the thickness of the mounting panel is between 0.5 and 3.2 mm. If, however, a Switch Guard or Dust
           Cover is used, the thickness of the mounting panel must be between 0.5 and 2 mm.
         • If the panel is to be finished with coating, etc., make sure that the panel meets the specified dimensions after
            coating.
         • Figures in parentheses are for Screw-less Clamp Connectors.
