5.1.3 Creation of Additional Drilled Holes and Through Holes by the Customer
Modify the device carefully and only in accordance with the safety notes
(see "Safety" section).
Calculate the usable area, see section 5.1.2.
Create additional through holes by 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!
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!

Additional Through Holes in the Enclosure with an internal Brass or Flange Plate
5.2.1 Creation of Additional Drilled Holes and Through Holes by R. STAHL
Give the following information to R. STAHL:
- Enclosure side
- Type
- Data sheet
- Quantity, manufacturers and approvals of the components that are to be installed.
R. STAHL
• will check whether the components, drilled hole diameters, quantity and position
correspond with the approval
• will create the drilled holes and through holes
• will mount the components
• will update the order documentation
• will carry out a routine test
• will, if necessary, fit a new type plate if the technical data has changed,
e.g. due to the components that are to be additionally installed.
Terminal boxes which the customer wants delivered without drilled holes are generally
marked as empty enclosures with the corresponding type plate (marking in accordance
with EN IEC 60079-7 and EN IEC 60079-0, as incomplete equipment "U" inside the
enclosure).
