EN 50173-3:2007

This European Standard specifies generic cabling that supports a wide range of communications services including automation, process control and monitoring applications for use within industrial premises comprising single or multiple buildings on a campus. It covers balanced cabling and optical fibre cabling.This European Standard is based upon and references the requirements of EN 50173-1. This European Standard contains additional requirements that are appropriate to industrial premises in which the maximum distance over which communications services have to be distributed is 10 000 m. The principles of this European Standard may also be applied to installations that do not fall within this range.In addition to the requirements of EN 50173-1, this European Standard specifies:a)a modified structure and configuration for generic cabling within industrial premises in which information technology applications are used to support process monitoring and control functions;b)implementation options; c)additional requirements that reflect the range of operating environments within industrial premises.Safety (electrical safety and protection, optical power, fire, etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of this European Standard and are covered by other Standards and regulations. However, information given in this European Standard may be of assistance in meeting these Standards and regulations.
