This Technical Report defines requirements and recommendations concerning limits for the application and operation of remote powering using cabling comprising balanced cabling components of Category 5 (minimum) as defined in EN 50173-1.
This Technical Report also describes:
-   a set of specific implementations which are the basis of a mathematical model for the temperature increases in bundles of cables under remote powering conditions;
-   a matching testing protocol used to provide data for the mathematical model;
NOTE   The testing protocol was established in order to enable comparison of data from different sources in order to support the development of the mathematical model and to develop appropriate planning and installation rules as suggested by different installation conditions. It is not the role of CLC/TC 215 to develop test methods for balanced, or other, cables and the protocol defined in Annex B is not as such a test method.
-   the mathematical model that is employed as the basis for the resulting requirements and recommendations.
Safety (electrical safety and protection, optical power, fire, etc.) and electromagnetic compatibility (EMC) requirements are outside the scope of this Technical Report and are covered by standards and regulations.
