Door interlocking for distributed industrial control panels according to UL 508A and NFPA 79
https://support.industry.siemens.com/cs/document/109762616/
To protect persons from injuries caused by electricity, control panels that are operated in USA must be designed so that they ensure proper protection against direct contact. This means that no live parts can be touched under normal operating conditions.
Relevant USA standards specify that doors of enclosures shall be interlocked when applied in industrial control panels (UL508A) for industrial machinery (NFPA79). At the same time, enclosures shall be accessible for maintenance and service purposes by qualified personnel. This application solution enables electrical engineers to comply easily with all requirements, while at the same time saving effort and costs.

The application example comprises 3 options:
Electronic door interlocking with LOGO!
Electric door interlocking
Electronic door interlocking with SIMATIC
