UNINTERRUPTIBLE POWER SYSTEMS (UPS) –
Part 2: Electromagnetic compatibility (EMC) requirements
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 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:
a) New UPS categories C1, C2, C3 replace previous “restricted and unrestricted sales
distribution” emission only related UPS categories “A, B 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.
---------------------- Page: 8 ----------------------
62040-2 IEC:2005 – 9 –
b) 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.
c) Lower a.c output interference voltage limits apply now for UPS with currents in excess of
100 A.
d) 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:
FDIS Report on voting
22H/74A/FDIS 22H/82/RVD

62040-2 IEC:2005 – 19 –
6 Emission
6.1 General
Disturbances in the frequency range from 0 Hz 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.
NOTE 1 The limits in this part of IEC 62040 may not, however, fully provide protection against interference to
radio and television reception when the UPS is used closer than 10 m to the receiving antenna for category C1 or
C2 UPS and 30 m for category C3 UPS.
NOTE 2 In special cases, for instance, when highly susceptible apparatus is being used in proximity, additional
mitigation measures may have to be employed to reduce the electromagnetic emission further below the specified
levels.
6.2 General requirements
UPS shall comply with the emission limits of 5.3 to 5.4.
The tests shall be made with the UPS in the following conditions:
– rated input voltage;
– normal and stored energy mode of operation;
– linear load that results in the highest interference level.
The objective of 5.4 is to define limits and test methods for UPS defined in the scope of this
part of IEC 62040 in relation to electromagnetic emissions which may cause interference in
other apparatus, for example, radio receivers.
These emission limits represent essential electromagnetic compatibility requirements.
Test requirements are specified for each port considered. Refer to Annex A for test
methodology.
6.3 General measurement conditions
6.3.1 General
The measurements shall be made in the operating mode producing the largest emission in the
frequency band being investigated consistent with normal applications. UPS operating modes
(normal mode and stored energy mode) shall be investigated.
An attempt should be made to maximise the emission by varying the test set-up configuration
of the test sample.
---------------------- Page: 14 ----------------------
62040-2 IEC:2005 – 21 –
For UPS with additional mains terminals (ports) for the connection of separate supplies for
static by-pass and/or maintenance by-pass circuits, these terminals (ports) shall, wherever
possible, be temporarily connected to the normal a.c. input port supply. Conducted emission
tests in 5.3 shall include measurement of these additional circuits.
If the UPS is part of a system or can be connected to auxiliary accessories, then the UPS shall
be tested while connected to the minimum configuration of auxiliary accessories necessary to
exercise the ports, or be terminated in an equivalent impedance.
UPS a.c. outputs shall be loaded with a linear load capable of operating the unit under test for
any load condition within its output rating.
The configuration and mode of operation during measurement shall be precisely noted in the
test report. Refer to Annex A for test set-up and measurement criteria. For in situ testing,
see Annex E. The tests shall be carried out within the specific operating environment range for
the UPS and at its rated supply voltage, unless otherwise indicated.
6.3.2 Documentation for the purchaser/user
a) The purchaser/user shall be informed if special measures have to be taken to achieve
compliance, for example, the use of shielded or special cables. Any restriction on the length
of the a.c. output cables shall also be indicated.
b) Notwithstanding that the scope of supply of
