scope:

This part of the IEC 62040 series of standards for uninterruptible power systems (UPS) 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 a.c. output voltage with port voltages not exceeding 1000 V a.c. or 1500 V d.c. 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. NOTE 1 - Typical UPS configurations include voltage and / or frequency converters and other topologies are described in Part 3 of IEC 62040, the test and performance product standard for UPS. NOTE 2 - UPS generally connect to their energy storage device through a d.c. link. A chemical battery is used throughout the standard as an example of an energy storage device. Alternative devices exist, and as such, where "battery" appears in the text of this standard, where applicable, this is to be understood as "energy storage device". This Part 1 specifies requirements to ensure safety for the ordinary person who may come into contact with the UPS and, where specifically stated, for the service person, who shall be a 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.
