40 This document has been prepared under a Standardization Request given to CENELEC by the European
41 Commission and the European Free Trade Association, and supports essential requirements of EU
42 Directive(s) / Regulation(s).
43 For the relationship with EU Directive(s) / Regulation(s), see informative Annex ZZ, which is an integral part of
44 this document.
45 1 Modification to Clause 1, “Scope”
46 Replace the text with the following:
47 “This document covers emission requirements related to radio-frequency (RF) disturbances and applies to
48 industrial, scientific and medical electrical equipment operating in the frequency range 0 Hz to 400 GHz and to
49 domestic and similar appliances designed to generate and/or use locally radio-frequency energy.
50 For ISM RF applications in the meaning of the definition found in the ITU Radio Regulations (see
51 Definition 3.13), this document covers emission requirements related to radio-frequency disturbances in the
52 frequency range of 9 kHz to 18 GHz.
53 Requirements for ISM RF lighting equipment and UV irradiators operating at frequencies within the ISM
54 frequency bands defined by the ITU Radio Regulations are contained in this document.
55 Equipment covered by other CISPR product and product family emission standards are excluded from the
56 scope of this document.”
57 2 Deletion of 3.19
58 Delete term entry 3.19.
59 3 Deletion of subclause 5.3
60 Delete the entire subclause 5.3.
61 4 Modification to subclause 6.1
62 Replace the text with the following:
63 “Class A equipment shall be measured either on a test site or when that is impossible due to size, complexity
64 or operating conditions, it may then be measured in situ.
65 Class B equipment shall be measured on a test site.
66 Measurements need only be performed in frequency ranges where limits are specified. The lower limit shall
67 apply at all transition frequencies.
68 Measuring apparatus and methods of measurement are specified in Clauses 7, 8 and 9.
69 Where this document gives options for testing against particular requirements with a choice of test methods,
70 compliance may be shown using any of those test methods, together with the specified limits and any relevant
71 restrictions.
72 NOTE In any situation involving the retesting of equipment, reproducibility of results is best achieved if the original
73 test method is used.”
74 5 Modification to subclause 6.2.1.3
75 Replace the table footnotes of Table 2 with the following footnotes:
76 “
a
These limits apply to equipment with a rated power > 20 kVA and intended to be connected to a dedicated power
transformer or generator, and which is not connected to low voltage (LV) overhead power lines. For equipment not
intended to be connected to a user specific power transformer the limits for ≤ 20 kVA apply. Information shall be provided
on installation measures that can be used to reduce emissions from the installed equipment. In particular it shall be
indicated that this equipment is intended to be connected to a dedicated power transformer or generator and not to LV
overhead power lines.
b
These limits apply only to high power electronic systems and equipment with a rated power greater than 75 kVA when
intended to be installed as follows:
— installation is supplied from a dedicated power transformer or generator, and which is not connected to Low Voltage
(LV) overhead power lines,
— installation is physically separated from residential environments by distance greater than 30 m or by a structure which
acts as a barrier to radiated phenomena,
— the product documentation shall indicate that this equipment meets the disturbance voltage limits for high power
electronic systems and equipment of rated input power > 75 kVA and provide information on installation measures to be
applied by the installer. In particular, it shall be indicated that this equipment is intended to be used in an installation which
is powered by a dedicated power transformer or generator and not by LV overhead power lines.
c
Selection of the appropriate set of limits shall be based on the rated a.c. power stated by the product documentation.
77 “
78 Replace the table footnotes of Table 3 with the following footnotes:
79 “
In certain frequency ranges, the limits in this table decrease linearly with logarithm of frequency.
a
Selection of the appropriate set of limits shall be based on the rated a.c. power stated by the product documentation.
b
These limits apply to equipment with a rated power > 20 kVA and intended to be installed in a large photovoltaic power
generating system by a professional. In the manual accompanying the product, information shall be provided on mitigation
measures that can be used to reduce emissions from the installed equipment, with the goal of preventing harmful
interference to radio reception in a distance of 30 m from the installation. In particular it shall be indicated that this
equipment can be equipped with additional filtering and that installation is physically separated from residential
environments by distance greater than 30 m. The installer is invited to check the mitigated installation against CISPR 11 in
situ measurements as indicated in Clause 6.4 of this document.
80 “
81 Replace the paragraph after Table 4 with the following:
82 “For diagnostic X-ray generators operating in intermittent mode the quasi-peak limits of Table 2 or Table 4 are
83 increased by 20 dB.”
84 Replace the table footer of Table 19 with the following:
85 “
L: maximum length of a cable (in metres) connected to an LV d.c. power port, and provided with the product or as
specified in the product documentation. Where no maximum cable length is specified, L shall be c
