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 non­governmental 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 a.ny 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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any equipment declared to be in conformity with an IEC Publication.

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. IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 62040-2 has been prepared by subcommittee 22H: Uninterruptible Power Systems (UPS), of IEC technical committee 22: Power electronic systems and equipment.

This second edition cancels and replaces the first edition published in 1999 and constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

1. New UPS categories C1, C2, C3 replace previous “restricted and unrestricted sales distribution” emission only related UPS categories “A, В and Table 2”. C1, C2, C3 take into account both emission and immunity requirements of the environment in which the UPS is intended to operate.

2. Mains terminal and a.c. output interference voltage limits apply now for UPS with currents in excess of 400 A. They are identical to those applying to UPS with currents in excess of 100 A.

3. Lower a.c output interference voltage limits apply now for UPS with currents in excess of 100 A.

4. Higher immunity requirements apply now for UPS intended to operate in commercial and industrial environments.

The text of this standard is based on the following documents:

Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table.

IEC 62040 consists of the following parts, under the general title Uninterruptible power systems (UPS):

Part 1-1: General and safety requirements for UPS used in operator access areas

Part 1-2: General and safety requirements for UPS used in restricted access locations

2. Electromagnetic compatibility (EMC) requirements

3. Method of specifying the performance and test requirements

The committee has decided that the contents of this publication will remain unchanged until the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in the data related to the specific publication. At this date, the publication will be

• reconfirmed;

• withdrawn;

• replaced by a revised edition, or

amended.UNINTERRUPTIBLE POWER SYSTEMS (UPS) -
Part 2: Electromagnetic compatibility (EMC) requirements

1. Scope

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.
