IEC 62040-1-2021 pdf free download – Uninterruptible power systems (UPS) – Part 1: Safety requirements.
This part of IEC 62040 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 ACoutput voltage with port voltages not exceeding 1 000 v AC or 1 500 v DC and that include an
energy storage device. lt applies to pluggable and to permanently connected UPs,whetherconsisting 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.
NOTE 1 TypicaluPs configurations, including voltage andor frequency converters and other topologies，aredescribed in lEC 62040-3,the test and performance product standard for UPs.
NOTE 2 uPs generally connect to their energy storage device through a DC link. A chemical battery is usedthroughout the standard as an example of an energy storage device.Altemative devices exist,and as such， where”battery””appears in the text of this document，this is to be understood as “energy storage device”.
This document specifies requirements to ensure safety for the ordinary person who comesinto contact with the uPs and, where specifically stated, for the skilled person . The objectiveis to reduce risks of fire，electric shock,thermal，energy and mechanical hazards during useand operation and, where specifically stated, during service and maintenance.
This product standard is harmonized with the applicable parts of group safety publicationIEC 62477-1:2012 forpowerelectronic converter systems and contains additionalrequirements relevant to UPs.
This document does not cover:. uPS that have a DC output;
systems for operation on moving platforms including，but not limited to， aircrafts，shipsand motor vehicles;
external AC or DC input and output distribution boards covered by their specific productstandard;
stand-alone static transfer systems (STS) covered by lEC 62310-1;
systems wherein the output voltage is directly derived from a rotating machine;. telecommunications apparatus other than uPs for such apparatus;
. functional safety aspects covered by lEC 61508(all parts).
NOTE 3 Even if this document does not cover the applications listed above, it is commonly taken as a guide forsuch applications.
NOTE 4 Specialized UPs applications are generally governed by additional requiremens covered elsewhere， forexample uPS for medical applications.
