BS EN 50153:2014 5 EN 50153:2014 Introduction It is generally accepted that safety depends on human factors, based on the normal behaviour of the operators involved, as well as upon technical factors. For these reasons

22、, this European Standard, in several instances, leaves a choice to the contracting parties between two alternatives. These alternatives consist of either the provision of operating rules, regulations and procedures, or in the application of technical measures such as mechanical or electrical interlo

23、cking devices. A list of the cases for which the contracting parties (e.g. user and manufacturer) should reach agreement before signing the contract is included in Annex B. BS EN 50153:2014EN 50153:2014 6 1 Scope This European Standard defines requirements to be applied in the design and manufacture

24、 of electrical installations and equipment to be used on rolling stock to protect persons from electric shocks. This European Standard is applicable to rolling stock of rail transport systems, road transport systems, if they are powered by an external supply (e.g. trolley buses), magnetically levita

25、ted transport systems and to the electrical equipment installed in these systems. This European Standard does not apply to: mine railways in mines, crane installations, moving platforms and similar transport systems on rails, funicular railways, temporary constructions. 2 Normative references The fo

32、.1.1.1 (electrically) instructed person person adequately advised or supervised by electrically skilled persons to enable them to perceive risks and to avoid hazards electricity can create 3.1.1.2 ordinary person person who is neither a skilled person nor an (electrically) instructed person 3.1.1.3

33、skilled person person who can judge the work assigned to him and recognize possible dangers on the basis of their professional training, knowledge and experience and of their knowledge of the relevant requirements 3.1.2 Other definitions 3.1.2.1 closed electrical operating area room or location whic

34、h serves exclusively for the operation of electrical equipment and is kept secure by a means appropriate to the voltage and location Note 1 to entry: Access to such areas is permitted only to skilled persons and (electrically) instructed persons. Note 2 to entry: The definition of closed electrical

35、operating area can be suitable for underfloor or upperroof cabinets. Generally speaking, it is any location (inside or outside the car body) which is kept secured because of the voltage that can assumed to be present on the equipment inside it. Access to such areas is not allowed for ordinary person
