Ta dokument zajema varnostne zahteve za postavitev napeljav informacijske tehnologije z daljinskim napajanjem z izmenično napetostjo delovanja,ki presega 50 V (efektivna vrednost), ali enosmerno napetostjo delovanja, ki presega 120 V, od prevodnika do prevodnika in/ali od prevodnika do ozemljitve. Uporablja se s standardoma EN 60950-1 [3] in EN 60950-21 [4] ter zajema izraze, zahteve in preskuse. Če se za napeljave in dele napeljav uporabljajo posebni standardi, imajo ti prednost, na primer standarda EN 60950-1 [3] in EN 60950-21 [4].

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.

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.
