Observe the following conditions when doing so:
 Leave enough distance to the circumferential seal (min. 3 mm/0.12 inch)
(see detail in figure).
 Modify the device carefully and only in accordance with the safety information
(see "Safety" chapter).
 Calculate the usable area.
 Create additional drilled holes through lasing or punching (drilling, hole cutting).
 When punching and cutting, make sure that the outer surfaces of the enclosure remain flat
and undamaged (without cracks).
 Determine the core hole diameter for threads. Do not use an NPT thread!
 Observe the mounting distances when creating the drilled holes.
 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 chapter 5.2 when subsequently equipping components!
 If the technical data has changed, e.g. due to the components that are to be additionally
installed, attach the new rating plate with the current values.
5.1.2.2 Enclosure with and without an internal Brass or Flange Plate
Calculate the usable area for cable entries in the enclosure
Important for the following calculation:
 Measure the dimensions on the plane surface inside of the enclosure
(not on the outside of the enclosure)
 Consider additional space required for blind rivet nuts. The space requirement for the
built-in part is determined using the width across corners of the cable entry plus
additional space for the tool.
The calculation is performed in three steps:
 Calculate the total usable area
 Calculate the required area for cable entries
 Calculate the remaining usable area.
