FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.

UNINTERRUPTIBLE POWER SYSTEMS (UPS) –
Part 2: Electromagnetic compatibility (EMC) requirements
1 Scope This part of IEC 62040 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. Subject to installing, operating and maintaining the UPS in the manner prescribed by the manufacturer, this standard defines emission limits, immunity levels, test methods and performance criteria for a complete UPS to comply with the essential EMC requirements necessary to avoid the UPS interfering with other apparatus, e.g. radio receivers, and to avoid the UPS being affected by external phenomena. This standard does not address EMC phenomena produced by loads connected to the UPS or situations created by any apparatus external to the UPS other than as described in the immunity requirements. This standard is harmonized with applicable IEC standards for electromagnetic emission limits and immunity levels. It contains additional requirements applicable to UPS. This standard does not cover: a) low-voltage DC power supply devices covered by IEC 61204 standards; b) systems wherein the output voltage is derived from a rotating machine. NOTE 1 UPS generally connect to their energy storage device through a DC link. A chemical battery is an example of an energy storage device. Alternative devices can be suitable, and as such, where “battery” appears in the text of this standard, this can be understood as “energy storage device”. NOTE 2 This type test-based product standard allows EMC conformity assessment of UPS included in one of categories C1, C2 and C3 before placing them on the market. It also provides guidance for conformity assessment of UPS included in category C4 (see Clause 4). NOTE 3 The differing test conditions necessary to encompass the range of physical sizes and power ratings of a complete UPS are taken into account. A complete UPS can consist of one or more interconnected units. For UPS configuration details refer to IEC 62040-3:2011, Annex A. NOTE 4 The requirements have been selected so as to permit an adequate level of EMC for UPS installed in residential, commercial, light industrial and industrial locations. The requirements are not always sufficient to cover situations with low probability of occurrence including UPS faults. 2 Normative references The following documents are referred to in the text in such a way that some or all of their content constitutes requirements of this document.

Category C3 UPS shall comply with category C3 requirements for emission limits (see Clause 5) and for immunity (see Clause 6). The following warning shall be included in the user manual. SIST EN 62040-2:2018
– 12 – IEC 62040-2:2016 © IEC 2016 WARNING: This is a product for commercial and industrial application in the second environment – installation restrictions or additional measures may be needed to prevent disturbances. 4.4 Category C4 UPS This category includes UPS that cannot be classified within any of the C1, C2 or C3 categories and intended for use in environments subject to particular requirements.
Such UPS shall meet the specific emission and immunity levels applicable for the installation. A category C4 UPS is not limited by current ratings. NOTE Conformity assessment of a C4 UPS generally consists of a technical evaluation of the effect of combining complying UPS variants and subassemblies, and of a final site test to verify compliance with requirements that cannot be readily verified by technical evaluation. For details regarding site testing refer to Annex E. 4.5 Categories and environment If the environment has been determined as the first environment, a category C1 or C2 UPS should be used. If the environment has been determined as the second environment, a category C2 or C3 UPS should be used. If the environment is not covered exclusively either by the first or second environment, a category C4 UPS should be used. From the emission point of view, a UPS with a lower emission category, such as C1, can always be used instead of one with a higher emission category, such as C3. Emission categories are independent of immunity. For example, a statement that a UPS has emission category C1 does not imply that the immunity is only suitable for the first environment. 4.6 Documentation For EMC purposes, the following shall be included in the user documentation: a) any special measures to be taken to achieve compliance, for example, the segregation of cables, the use of shielded or special cables and any restriction on the length of cables connected to the AC output and/or to the energy storage device; b) upon request, a list of EMC-compatible UPS accessories; c) warning notice for category C1 UPS as described in 6.3.2; d) warning notice for category C2 and category C3 UPS as applicable and as described in 4.2 and 4.3. 5 Emission 5.1 General The applicable emission limits for each UPS category are specified in 5.3. Emissions in the frequency range up to 1,0 GHz are covered. The emission requirements have been selected so as to ensure that disturbances generated by UPS operating normally do not reach a level which could prevent other apparatus from operating as intended.

systems (UPS), of IEC technical committee 22: Power electronic systems and equipment.
The text of this interpretation sheet is based on the following documents:

Interpretation of 5.3.2.4, Limits at the network ports
Introduction
Sub-clause 5.3.2.4 states that the network port limits applicable to UPS of category C1, C2
and C3 are located in Table 1, Table 2 and Annex C.
It was not clear whether 5.3.2.4 applies to network ports that originate and terminate within
the enclosure port of the UPS (i.e. to network ports connected exclusively to circuits or
devices forming an integral part of the UPS).
Interpretation
The network port limits in Table 1, Table 2 and Annex C apply only to network ports for
which connection to circuits or devices external to the enclosure port of the UPS is allowed.
This includes, without limitation, connection to PSTN, ISDN, xDSL and Ethernet networks.
The limits in Table 1, Table 2 and Annex C do not apply to network ports that originate and
terminate within the enclosure port of the UPS (i.e. to network ports connected exclusively
to circuits or devices forming an integral part of the UPS).

UNINTERRUPTIBLE POWER SYSTEMS (UPS) –
Part 2: Electromagnetic compatibility (EMC) requirements
1 Scope
This part of IEC 62040 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.
Subject to installing, operating and maintaining the UPS in the manner prescribed by the
manufacturer, this standard defines emission limits, immunity levels, test methods and
performance criteria for a complete UPS to comply with the essential EMC requirements
necessary to avoid the UPS interfering with other apparatus, e.g. radio receivers, and to avoid
the UPS being affected by external phenomena.
This standard does not address EMC phenomena produced by loads connected to the UPS or
situations created by any apparatus external to the UPS other than as described in the
immunity requirements.
This standard is harmonized with applicable IEC standards for electromagnetic emission limits
and immunity levels. It contains additional requirements applicable to UPS.
This standard does not cover:
a) low-voltage DC power supply devices covered by IEC 61204 standards;
b) systems wherein the output voltage is derived from a rotating machine.
NOTE 1 UPS generally connect to their energy storage device through a DC link. A chemical battery is an
example of an energy storage device. Alternative devices can be suitable, and as such, where “battery” appears in
the text of this standard, this can be understood as “energy storage device”.
NOTE 2 This type test-based product standard allows EMC conformity assessment of UPS included in one of
categories C1, C2 and C3 before placing them on the market. It also provides guidance for conformity assessment
of UPS included in category C4 (see Clause 4).
NOTE 3 The differing test conditions necessary to encompass the range of physical sizes and power ratings of a
complete UPS are taken into account. A complete UPS can consist of one or more interconnected units. For UPS
configuration details refer to IEC 62040-3:2011, Annex A.
NOTE 4 The requirements have been selected so as to permit an adequate level of EMC for UPS installed in
residential, commercial, light industrial and industrial locations. The requirements are not always sufficient to cover
situations with low probability of occurrence including UPS faults.
