UNINTERRUPTIBLE POWER SYSTEMS (UPS) –
Part 1-1: General and safety requirements for UPS
used in operator access areas
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 62040-1-1 has been prepared by subcommittee 22H: Uninter-
ruptible power systems (UPS), of IEC technical committee 22: Power electronic systems and
equipment.
This bilingual version (2004-02) replaces the English version and its corrigenda 1 (2002-12)

UNINTERRUPTIBLE POWER SYSTEMS (UPS) –
Part 1-1: General and safety requirements for UPS
used in operator access areas
1 Scope and specific applications
1.1 Scope
This part of IEC 62040 applies to electronic uninterruptible power systems (UPS) with an
electrical energy storage device in the d.c. link. It is to be used with IEC 60950-1 which is
referred to in this standard as "RD".
When any item is referred to by the phrase "The definitions or the provisions of item/RD
apply", this phrase is intended to mean that the definitions or provisions in that item of
IEC 60950-1 apply, except any which are clearly inapplicable to uninterruptible power
systems. National requirements additional to those in IEC 60950-1 apply and are found as
notes under relevant clauses of the RD.
The primary function of the UPS covered by this standard is to ensure continuity of an
alternating power source. The UPS may also serve to improve the quality of the power source
by keeping it within specified characteristics.
This standard is applicable to UPS which are movable, stationary, fixed or for building-in, for
use on low-voltage distribution systems and intended to be installed in any operator
accessible area. It specifies requirements to ensure safety for the operator and layman who
may come into contact with the equipment and, where specifically stated, for the service
person.
This standard is intended to ensure the safety of installed UPS, both as a single UPS unit or
as a system of interconnected UPS units, subject to installing, operating and maintaining the
UPS in the manner prescribed by the manufacturer.
This standard does not cover d.c. supplied electronic ballasts (IEC 61347 and IEC 60925),
UPS intended to be installed in separated electrical locations and UPS based on rotating
machines.
The relevant general and safety requirements for UPS installed in restricted access locations
are given in IEC 62040-1-2; electromagnetic compatibility (EMC) requirements and definitions
are given in IEC 62040-2.
1.2 Specific applications
Even if this standard does not cover all types of UPS, it may be taken as a guide for such
equipment. Requirements additional to those specified in this standard may be necessary for
specific applications, for example:
– UPS intended for operation while exposed, for example, to extremes of temperature; to
excessive dust, moisture, or vibration; to flammable gases; to corrosive or explosive
atmospheres;
---------------------- Page: 11 ----------------------
62040-1-1 IEC:2004 – 13 –
– electromedical applications with the UPS located within 1,5 m from the patient contact
area;
– for UPS subject to transient overvoltages exceeding those for Overvoltage Category II
according to IEC 60664, additional protection might be necessary in the mains supply to
the UPS;
– UPS intended for use where ingress of water and foreign objects are possible, additional
requirements may be necessary; for guidance on such requirements and for relevant
testing, see annex H;
– UPS with trapezoidal output waveforms and long run times (greater than 30 min) in
addition to complying with 5.3.1.2 of IEC 62040-3 are subject to voltage distortion tests for
the purpose of load compatibility.
NOTE For UPS intended to be used in vehicles, on board ships or aircraft, in tropical countries, or on elevations
greater than 1 000 m, different requirements may be necessary.

3 Definitions
3.1 General
For the purposes of this standard, the following definitions apply as well as some of the
definitions of IEC 60950-1. Where the terms "voltage" and "current" are used, they imply the
r.m.s. values, unless otherwise specified.
NOTE Care should be taken that measurement instruments give a true r.m.s. reading in the presence of non-
sinusoidal signals.
3.1.1
uninterruptible power system (UPS)
combination of convertors, switches and energy storage devices (for example, batteries),
constituting a power system for maintaining continuity of load power in case of input power
failure
3.1.2
bypass
power path alternative, either internal or external to the UPS
3.1.3
primary power

inspection or by testing of properties, it is permitted to confirm compliance by reviewing any
relevant data or previous test results that are available instead of carrying out the specified
type tests.
NOTE For physically large units and/or power ratings, adequate test facilities to demonstrate some of the type
tests may not exist.
This situation also applies to some electrical tests for which no commercial test simulation
