Short definition
2D & 3D enclosure planning comprises the systematic design and documentation of enclosures for industrial automation systems. It includes the spatial arrangement of PLC components, power electronics, terminals, fuses and auxiliary devices as well as the complete electrotechnical documentation in accordance with DIN EN 61439. Modern CAE software such as EPLAN Electric P8 or AutoCAD Electrical enables end-to-end planning from circuit diagrams and terminal diagrams to three-dimensional visualization. The planning forms the basis for standard-compliant enclosure construction and efficient commissioning.
Functional principle
2D planning creates standard-compliant circuit diagrams, overview diagrams and terminal diagrams with clear equipment identifiers in accordance with IEC 81346. 3D planning supplements this with the spatial visualization of all components, wiring routes and mounting points in the virtual enclosure model. Thermal calculations, EMC requirements and maintenance accessibility are already taken into account during the planning phase. The software automatically generates parts lists, cable lists and production documents. Collision checks and space optimization reduce planning errors and speed up production considerably.
Areas of application
Professional control cabinet planning is essential for all automated membrane filtration systems with complex control and drive technology. It ensures the safe integration of frequency inverters, motor protection switches, safety components and communication modules. The structured documentation makes subsequent expansions, troubleshooting and maintenance work considerably easier.
Typical areas of application:
- Compact control cabinets for mobile filtration systems
- Air-conditioned cabinets for PLC installation close to the process
- Explosion-proof versions for ATEX areas
- Redundant control systems in critical infrastructures
- Modular enclosure concepts for scalable system expansions
Summary
Sophisticated 2D & 3D enclosure planning minimizes production times, reduces sources of error and significantly lowers assembly costs. It enables precise material procurement, optimized space utilization and meets normative requirements such as CE conformity and UL certification. For plant engineers and control cabinet manufacturers, it is indispensable for cost-effective project implementation, quality assurance and the long-term maintainability of automated filtration systems.
