Before customization, provide device models, dimensions, weight, panel/interface drawings, mounting methods, cable counts and entry directions, thermal needs, materials, surface finishes, and operating environments. For PC enclosures, include host and display specs; for panel enclosures, cutout drawings; for DIN-rail enclosures, component lists and rail mounting requirements.

Specify whether IP65 is a design target or a mandatory acceptance test standard, and confirm if test setups include displays, pushbuttons, fans, cable glands, and accessories. Complete drawings, samples, or on-site photos help determine the structure. The final IP rating depends on fully assembled testing or technical documentation.
