(Main)Uninterruptible power systems (UPS) - Part 1: Safety requirements
Uninterruptible power systems (UPS) - Part 1: Safety requirements
IEC 62040-1:2017 applies to movable, stationary, fixed or built-in UPS for use in low-voltage distribution systems and that are intended to be installed in an area accessible by an ordinary person or in a restricted access area as applicable, that deliver fixed frequency AC output voltage with port voltages not exceeding 1 000 V AC or 1 500 V DC and that include an energy storage device. It applies to pluggable and to permanently connected UPS, whether consisting of a system of interconnected units or of independent units, subject to installing, operating and maintaining the UPS in the manner prescribed by the manufacturer. This document specifies requirements to ensure safety for the ordinary person who comes into contact with the UPS and, where specifically stated, for the skilled person. The objective is to reduce risks of fire, electric shock, thermal, energy and mechanical hazards during use and operation and, where specifically stated, during service and maintenance. This product standard is harmonized with the applicable parts of group safety publication IEC 62477-1:2012 for power electronic converter systems and contains additional requirements relevant to UPS. This edition includes the following significant technical change with respect to the previous edition: the reference document has been changed from IEC 60950-1:2005 (safety for IT equipment) to IEC 62477-1 (group safety standard for power electronic converters).
Unterbrechungsfreie Stromversorgungssysteme (USV) - Teil 1: Sicherheitsanforderungen
Alimentations sans interruption (ASI) - Partie 1: Exigences de sécurité
IEC 62040-1:2017 s'applique aux ASI mobiles, stationnaires, fixes ou intégrées destinées à une utilisation dans des réseaux de distribution basse tension et à être installées dans une zone accessible par une personne ordinaire ou une zone d'accès restreint, selon le cas, qui fournissent une tension de sortie en courant alternatif à fréquence fixe avec des tensions au niveau de la connexion ne dépassant pas 1 000 V en courant alternatif ou 1 500 V en courant continu, et qui incluent un dispositif de stockage de l'énergie. Elle s'applique aux ASI alimentées par une prise de courant et aux ASI raccordées en poste fixe, qu'elles soient sous la forme d'un système d'équipements interconnectés ou d'équipements indépendants destinés à être installés, à fonctionner et à être entretenus de la manière prescrite par le constructeur. Le présent document spécifie des exigences destinées à garantir la sécurité des personnes ordinaires qui peuvent entrer en contact avec l'ASI et, lorsque cela est spécifiquement précisé, des personnes qualifiées. L'objectif est de réduire les risques d'incendie, de choc électrique, ainsi que les risques thermiques, mécaniques ou liés au niveau d'énergie pendant l'utilisation, le fonctionnement et, si spécifiquement indiqué, pendant l'entretien et la maintenance. Cette norme de produits a été harmonisée avec les parties applicables de la publication groupée de sécurité IEC 62477-1:2012 relative aux systèmes électroniques de conversion de puissance et contient des exigences supplémentaires pertinentes pour les ASI. Cette édition inclut la modification technique majeure suivante par rapport à l'édition précédente: le document de référence n'est plus l'IEC 60950-1:2005 (sécurité applicable aux matériels de traitement de l'information) mais l'IEC 62477-1 (norme groupée de sécurité applicable aux convertisseurs électroniques de puissance).
Sistemi z neprekinjenim napajanjem (UPS) - 1. del: Varnostne zahteve (IEC 62040-1:2017)
Ta standard se uporablja za premične, stacionarne, fiksne ali vgrajene sisteme z neprekinjenim napajanjem za uporabo v nizkonapetostnih razdelilnih sistemih, ki so namenjeni vgradnji na katero koli mesto, dostopno laikom, ali na ustrezne lokacije z omejenim dostopom, ki pri fiksni frekvenci zagotavljajo izhodno izmenično napetost, pri čemer vrednosti na vratih ne presegajo 1000 V izmenične napetosti ali 1500 V enosmerne napetosti, ter vključujejo napravo za shranjevanje električne energije. Uporablja se za stalno priklopljene sisteme z neprekinjenim napajanjem, če je sistem sestavljen iz vzajemno povezanih enot ali samostojnih enot, upoštevajoč namestitev, uporabo in vzdrževanje sistema z neprekinjenim napajanjem na način, ki ga je predpisal proizvajalec. Obstajajo tudi druge naprave. Ko se torej v besedilu tega dokumenta pojavi »baterija«, se to lahko razume kot »naprava za shranjevanje energije«. Ta dokument določa zahteve za zagotavljanje varnosti laikov, ki pridejo v stik s sistemom z neprekinjenim napajanjem, in (če je to izrecno omenjeno) strokovnjakov. Cilj je zmanjšanje tveganja požara, elektrošoka, toplotnih, energijskih in mehaničnih tveganj med uporabo, delovanjem ter, kjer je to navedeno, popravilom in vzdrževanjem. Ta standard za izdelke je usklajen z ustreznimi deli publikacije skupinske varnosti IEC 62477-1:2012 za električne močnostne pretvorniške sisteme in vsebuje dodatne zahteve, pomembne za sisteme z neprekinjenim napajanjem. Ta dokument ne zajema: – sistemov z neprekinjenim napajanjem brez enosmernega izhoda; – sistemov za delovanje na premičnih platformah, kar med drugim vključuje letala, ladje in motorna vozila; – zunanjih izmeničnih in enosmernih vhodnih in izhodnih električnih razdelilnikov, ki so zajeti v posebnih standardih za izdelke; – samostojnih sistemov s statičnim prenosom (STS), ki so zajeti v standardu IEC 62310-1; – sistemov, ki izhodno napetost pridobivajo iz vrteče se naprave; – telekomunikacijskih naprav, ki niso sistemi z neprekinjenim napajanjem teh naprav; – funkcionalne varnosti, ki jo zajema standard IEC 61508 (vsi deli).
