EMC@ resistibility and safety requirements and guidance for determining responsibility under co-located information and communication technology installations (Study Group 5)
The purpose of this Recommendation is to provide guidance aimed at ensuring safe and problem-free operation in co-located information and communication technology (ICT) installations from the viewpoint of electromagnetic compatibility (EMC)@ resistibility and safety. This Recommendation deals with the following environments where equipment owned by several operators can be installed: ?C telecommunication centres; ?C data centres; ?C remote electronic sites; ?C in some instances@ the customer premises when the equipment owned by operators is installed in that environment. Minimum requirements are given in this Recommendation in order to ensure safe and problem-free operation and to reduce EMC@ resistibility and safety problems. The main aspects are: safety for humans and equipment; electromagnetic emission and immunity; resistibility against overvoltage and overcurrent; and earthing. The procedures and countermeasures that are used in case of problems are also described in this Recommendation. Also@ this Recommendation provides guidance on determining responsibility when an EMC problem occurs. If national regulations or agreements for co-location between operators exists@ then this Recommendation supports the items that these documents do not cover. Requirements that are not related to EMC@ resistibility and safety are outside the scope of this Recommendation.
