ETSI ETSI EN 302 999 V1.2.1 (2013-03) 5 1 Scope The present document contains safety requirements for the erection of information technology installations with remote power feeding at an operating a.c. voltage exceeding 50 V (rms value) or an operating d.c. voltage exceeding 120 V, conductor to conductor and/or conductor to earth. It applies in addition to EN 60950-1 [3] and EN 60950-21 [4] and contains terms, requirements and tests. If special standards are applicable for installations and parts of installations these will take precedence; for example EN 60950-1 [3] and EN 60950-21 [4]. 2 References References are either specific (identified by date of publication and/or edition number or version number) or non-specific. For specific references, only the cited version applies. For non-specific references, the latest version of the reference document (including any amendments) applies. Referenced documents which are not found to be publicly available in the expected location might be found at http://docbox.etsi.org/Reference.

NOTE 2: For information technology equipment see EN 60950-1 [3]. remote power feeding point: remote power feeding point supplies remote power feeding circuits with electrical current via its remote power feeding equipment remote power feeding section: part of remote power feeding circuits located between a remote power feeding point and the immediately following power-fed point, or between two adjacent power-fed points RFT-C circuit: RFT circuit which is so designed and protected that under normal operating conditions and single fault conditions, the currents in the circuit do not exceed defined values NOTE: See EN 60950-21 [4]. RFT-V circuit: RFT circuit which is so designed and protected that under normal operating conditions and single fault conditions, the voltages are limited and the accessible area of contact is limited NOTE: See EN 60950-21 [4]. type of remote power feeding: electrical operating mode of the remote power feed in a remote power feeding circuit. It is specified by particular characteristics of the circuit configuration and power feeding method. A distinction is ma
