Uninterruptible power systems (UMS). Part 2: EMC requirements

This EMC 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 will take 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. It takes account of the 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 i
