prEN IEC 63494-1:2024

This document specifies the safety requirements for electro-mechanical interfaces connecting lighting system devices to luminaires. These interfaces are used to mechanically connect, electrically power, and enable communication of lighting system devices on luminaires . Electro-mechanical interfaces up to and including 1 000 V AC or 1 500 V DC are included. The document specifies safety related mechanical, electrical, ambient conditions, and construction requirements for the interface components including protective covers. Specific requirements for the devices that can utilize the interface such as sensors, communication modules, cameras, etc. are out of scope for this document.
The document does not specify the following aspects:
• The lighting technology
• The illumination performance
• Data communication
• Functional safety
• The performance and interchangeability of devices on the interface
• Electromagnetic compatibility (EMC)
The document does not specify safety for the following:
• Product safety covered in existing standards (e.g. control gear, light sources, luminaires, electrical connectors, PoE, USB)
• Device safety aspects for devices using the electro-mechanical interface
• Couplers for mains input power to the luminaire.
The purpose of IEC 63494-1 is to provide a set of requirements and tests which are considered generally applicable to electro-mechanical interfaces. Detailed requirements for particular electro-mechanical interfaces are specified in the IEC 63494-2 series.
NOTE: If the electro-mechanical interface is not standardized in the IEC 63494-2 series then interchangeability aspects are not covered.
NOTE: Although manual operation is anticipated at this time, future use of insertion and removal tools can be utilized and covered by this safety standard.
