Specifies electromagnetic compatibility (EMC) requirements for uninterruptible power systems (UPS) - both single units and systems comprising interconnected UPS with associated control/switchgear. This Standard takes precedence over all aspects of generic EMC Standard and no additional testing is necessary.

This International Standard applies to single UPS units or UPS systems comprising a number of interconnected UPS and associated control/switchgear forming a single power system, intended to be installed in any operator accessible area or in separated electrical locations, connected to either industrial or public low voltage supply networks.This product EMC standard takes precedence over all aspects of the generic standards, and no additional testing is necessary.The requirements have been selected so as to ensure an adequate level of electromagnetic compatibility (EMC) for UPS at public and industrial locations. These levels cannot, however, cover extreme cases which may occur in any location, but with extremely low probability of occurrence.It takes into account differing test conditions necessary to encompass the range of physical sizes and power ratings of UPS.A UPS unit or system shall meet the relevant requirements of this standard as a stand-alone product. EMC phenomena produced by any customers' load connected to the output of the UPS equipment shall not be taken into account.Special installation environments are not covered, nor are fault conditions of UPS taken into account.This standard does not cover d.c. supplied electronic ballast (IEC 60924 and IEC 60925) or UPS based on rotating machines.This standard states:– EMC requirements;– test methods;– minimum performance levels.
