5.2.4 Creation of Additional Drilled Holes and Through Holes in the Enclosure with Flange Plate by
the Customer
 Modify the device carefully and only in accordance with the safety notes
(see "Safety" section).
 Calculate the usable area for built-in components, see sections 5.1.2 and 5.2.2.
 Select a space/area for the cable entry on the flange plate anywhere inside the collision
frame (see thin line in figure). Ensure that screw connections made later do not go beyond
this collision frame. Leave enough distance (min. 15 mm) to the circumferential frame
(see the figure for the "Collision frame" section).
All dimensions in mm [inches]

 When punching and cutting, make sure that the outer surfaces of the enclosure remain flat
and undamaged (without cracks).
 When determining the through holes, observe the mounting distances.
 Adjust the hole diameters to the dimensions of the built-in parts or their seals.
 ONLY use built-in components with flat seal (gasket).
 Observe section 5.3 when subsequently equipping components!
