IEC 62040-1:20 17适用于低压配电系统中使用的移动式、固定式、固定式或内置式UPS，这些UPS旨在安装在普通人可进入的区域或限制进入的区域（如适用），提供固定频率的交流输出电压，端口电压不超过1 000 V AC或1 500 V DC，并且包括储能设备。它适用于可插拔和永久连接的UPS，无论是由互连单元系统还是独立单元组成，但须按照制造商规定的方式安装、操作和维护UPS。 本文件规定了确保接触UPS的普通人以及（如有特别说明）技术人员安全的要求。目标是降低使用和操作期间以及特别说明的服务和维护期间的火灾、电击、热、能量和机械危害的风险。 本产品标准与团体安全出版物IEC 62477-1:20 12中电力电子转换器系统的适用部分相协调，并包含与UPS相关的附加要求。 与上一版相比，本版包括以下重大技术变更:参考文件从IEC 60950-1:20 05（IT设备安全）变更为IEC 62477-1（电力电子转换器团体安全标准）。

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).
