IEC 62040-2:2016 is a type test product standard for electromagnetic compatibility (EMC) and applies to movable, stationary, fixed or built-in, pluggable and permanently connected UPS for use in low-voltage distribution systems with an environment being either residential, commercial, light industrial or industrial, which deliver output voltage with port voltages not exceeding 1 500 V DC or 1 000 V AC and which include an energy storage device. This edition includes the following significant technical changes with respect to the previous edition:
a) the inclusion of network port limits in Table 1, Table 2 and Annex C for the sake of consistency with other standards;
b) a change of quasi-peak limit for category C3 UPS in Table 2 for the sake of consistency with other standards;
c) a clarification in Table 4 about the performance criteria for immunity tests;
d) a revision of some test configurations in Annex A.
