The purpose of this Recommendation is to ensure safe and problem-free operation for connections to unbundled cables. This Recommendation is applied when equipment or a system is connected to unbundled cables. Minimum requirements are given in this Recommendation in order to ensure safe and problem-free operation and to reduce trouble related to electromagnetic compatibility (EMC)@ safety and resistibility. The main aspects are safety for humans and equipment@ emission and immunity@ resistibility of equipment against overvoltage and overcurrent and mutual interference. Requirements that are not related to EMC@ safety and resistibility@ are outside the scope of this Recommendation.
