Annex E Declaration of design (normative)

Defines passive filter units for electromagnetic interference suppression which fall within the scope of the Generic Specification EN 133000. Specified according to this specification will either be connected to mains supplies, when compliance with the mandatory tests of Table 2 is necessary, or used on other circuit positions where the equipment specification prescribes that some or all of these safety tests are required. Applies to those connected to an a.c. mains or other supply with a nominal voltage not exceeding 1000 V a.c. (r.m.s.) or 1000 V d.c. with a nominal frequency not exceeding 400 Hz.
