12、ETSI standards approval procedure. The present ETS constitutes a subpart of a multi-part ETS as shown below: ETS 300 386 Equipment Engineering (EE); Public telecommunication network equipment Electromagnetic Compatibility (EMC) requirements Part 1: Part 2: Product family overview, compliance criteri
13、a and test levels Product specific compliance criteria and operating conditions Subpart 1: Switching equipment Subpart 2: Transmission equipment Subpart 3: Power supply equipment Subpart 4: Supervisory equipment This ETS has been prepared in response to European Commission mandate BC-T-353 and, upon
14、 citation in the Official Journal of the European Communities, is intended to become a Harmonized Standard within the terms of the New Approach.

18、lecommunications Standard (ETS) defines the product-specific specific performance criteria and operating conditions for power supply equipment intended to be used within a public telecommunication network. Such equipment includes: - central power plant; - end of suite power supplies: - uninterruptib
19、le power supply (UPS); - stabilized AC power supply; - and other dedicated telecommunication network power supplies. This ETS specifies the operating conditions and the minimum compliance criteria for such equipment. The applicable EMC tests, the method of measurements and the limits are specified i
20、n ETS 300 386-1 l, from which the EMC requirements are selected taking into account the priority of service provided by the equipment under consideration. The environmental classification used in this ETC refers to ETS 300 386-1 I. The requirements of this ETS do not cover those cases where a potent
21、ial source of interference which produces individually repeated transient phenomena or continuous phenomena is permanently present, e.g., a radar or broadcast site in the near vicinity. In such cases it may be necessary to use special protection applied to either the source of interference or the eq
22、uipment interfered with, or both. Power supply equipment which is uniquely associated with or integrated in other equipment is outside the scope of this ETS. Equipment for cabled distribution systems for television and sound signals as defined in EN50083-2 26 is outside the scope of this ETS. 2 Norm
23、ative references This ETS incorporates by dated and undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these
24、 publications apply to this ETS only when incorporated in it by amendment or revision.
