适用范围：This part of IEC 62040 applies to UPS units intended to be installed - as a unit or in UPS systems comprising a number of interconnected UPS and associated control/switchgear forming a single power system; and - in any operator accessible area or in separated electrical locations, connected to low-voltage supply networks for either industrial or residential, commercial and light industrial environments. This part of IEC 62040 is intended as a product standard allowing the EMC conformity assessment of products of categories C1, C2 and C3 as defined in this part of IEC 62040, before placing them on the market. Equipment of category 4 is treated as a fixed installation. Checking is generally done after installation in its final place of use. Sometimes partial checking may be done before. See Annex E 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. This part of IEC 62040 takes into account 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 part of IEC 62040 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 part of IEC 62040 does not cover d.c. supplied electronic ballast or UPS based on rotating machines. This part of IEC 62040 states: - EMC requirements; - test methods; - minimum performance levels.
