Description

This part of EN 50397 provides general recommendations for the selection, storage, transportation and installation of the covered conductors and the related accessories specified in EN 50397 1 and EN 50397 2, unless otherwise specified. Safety regulations and environmental regulations as well as rules for installation and mechanical design are not considered in this Guide to use, as they are covered by relevant national regulations and laws. Relevant national regulations are not considered in this guide, but it is advised that they are always consulted as appropriate. NOTE The term ‘national regulations’ is used throughout this guide. It can include specific safety regulations, rules of installation and other relevant instructions which, depending upon the particular country or district, can exist in a legislative (mandatory) form, or as a non-mandatory code of practice. In addition, certain specific utilities can have their own safety practices. It is assumed that the design of installations, the purchase and installation of covered conductors and of the related accessories specified in this document are entrusted to suitably skilled and competent people. In case of doubt as to the suitability of covered conductors and the related accessories for a particular use, further specific information is expected to be obtained from the manufacturer.
