V tem dokumentu izraz visokonapetostna (HV) oprema zajema nizkonapetostno (LV) opremo, ki je nepogrešljiv sestavni del opreme, ki deluje pri visoki napetosti. Zahteve v tem dokumentu zadevajo predvsem dele, ki delujejo pri visoki napetosti, razen kadar je izrecno navedeno drugače.
OPOMBA 1: Oprema, ki ni sestavni del visokonapetostne opreme, je obravnavana v standardu IEC 60204-1:2016.
OPOMBA 2: V tem dokumentu izraz »električni« zajema tako električne kot elektronske zadeve (tj. električna oprema pomeni tako električno kot tudi elektronsko opremo).
OPOMBA 3: Ta dokument se ne uporablja za neodvisne visokonapetostne napajalne inštalacije, za katere obstajajo posebni standardi IEC.
Električna oprema, ki je zajeta v tem dokumentu, se začne na točki povezave z napajanjem električne opreme stroja (glej točko 5.1).
OPOMBA 4: Zahteve za visokonapetostne napajalne inštalacije najdete v standardu IEC 61936-1. Ta dokument je splošni varnostni standard. Ne zajema vseh zahtev (npr. varovanja, spajanja ali nadzora), ki so potrebne ali zahtevane zaradi drugih standardov ali predpisov za zaščito osebja pred nevarnostmi, ki niso pogojene z virom električne energije. Vsaka vrsta stroja vključuje edinstvene zahteve, ki jih je treba izpolniti za zagotovitev ustrezne varnosti.
OPOMBA 5: Pri nekaterih strojih je lahko visokonapetostni napajalnik proizveden z blokovnim transformatorjem (avtotransformator), ki se napaja z nizkonapetostnim sistemom (npr. z nizkonapetostnim generatorjem).
OPOMBA 6: V okviru tega dokumenta izraz »oseba« zajema vse posameznike; »osebje« so tiste osebe, ki so dodeljene za uporabo ter vzdrževanje te opreme in ki jim je to naročil uporabnik ali njegov zastopnik.
Ta del standarda IEC 60204 vključuje zlasti (vendar ni omejen na) stroje, kot je opredeljeno v točki 3.29
(Dodatek A navaja primere strojev, katerih električno opremo je mogoče zajeti s tem dokumentom.).
Za zaščito pred električnim udarom z visokonapetostno opremo se ta dokument nanaša na standard IEC 61936-1. V zvezi z nizkonapetostno opremo se ta dokument nanaša na standard IEC 602041: 2016.
OPOMBA 7: V visokonapetostnih in nizkonapetostnih standardih se uporabljajo različni izrazi za zaščito pred električnim udarom. V visokonapetostnih standardih se uporabljata izraza »neposredni stik« in »posredni stik«, v nizkonapetostnih standardih pa se uporabljata izraza »osnovna zaščita« in »zaščita ob okvari«.
Dodatne in posebne zahteve lahko veljajo za električno opremo strojev, ki:
– se uporabljajo na prostem (tj. zunaj zgradb ali drugih zaščitnih struktur);
– uporabljajo, obdelujejo ali proizvajajo potencialno eksplozivni material (na primer barvo ali žagovino);
– so namenjeni uporabi v potencialno eksplozivnih in/ali vnetljivih atmosferah;
– predstavljajo posebna tveganja pri proizvodnji ali uporabi nekaterih materialov;
– se uporabljajo v rudnikih.
Nevarnosti, ki so posledica hrupa in vibracij, niso obravnavane v tem dokumentu.

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. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60204-11 has been prepared by IEC technical committee 44:
Safety of machinery – Electrotechnical aspects.
This second edition cancels and replaces the first edition, published in 2000. This edition
constitutes a technical revision.
This edition contains significant technical changes with respect to the previous edition
regarding the following:
– aspects of risk assessment, which are mirrored from ISO 12100;
– equipotential bonding and earthing;

INTRODUCTION
This part of IEC 60204 provides requirements and recommendations relating to the high-
voltage electrical equipment (HV equipment) of machines together with its associated low-
voltage electrical equipment (LV equipment) so as to promote
– safety of persons and property,
– consistency of control response,
– maintainability.
Figure 1 is a block diagram of a machine and associated equipment showing the various
elements of the electrical equipment addressed in this document. Numbers in parentheses
(…) refer to clauses and subclauses in this document. It is understood that all of the elements
taken together including the safeguards, software and the documentation constitute the
machine or group of machines working together with usually at least one level of supervisory
control.
This document should be used in conjunction with IEC 60204-1. HV equipment can include LV
control parts in the same general enclosure or in separate compartments.

Part 11: Requirements for equipment for voltages
above 1 000 V AC or 1 500 V DC and not exceeding 36 kV

1 Scope
This part of IEC 60204 applies to electrical and electronic equipment and systems to
machines, including a group of machines working together in a co-ordinated manner, which
operate at nominal voltages above 1 000 V AC or 1 500 V DC and not exceeding 36 kV AC or
DC with nominal frequencies not exceeding 60 Hz.
In this document, the term HV equipment also covers the LV equipment forming an integral
part of the equipment operating at high voltage. The requirements in this document primarily
cover the parts operating at high-voltage except where explicitly stated otherwise.
NOTE 1 LV equipment not forming part of the HV equipment is covered by IEC 60204-1:2016.
NOTE 2 In this document, the term "electrical" includes both electrical and electronic matters (i.e. electrical
equipment means both the electrical and the electronic equipment).
NOTE 3 This document does not apply to independent high-voltage power supply installations for which separate
IEC standards exist.
The electrical equipment covered by this document commences at the point of connection of
the supply to the electrical equipment of the machine (see 5.1).
NOTE 4 For the requirements for high-voltage power supply installations, see IEC 61936-1.
This document is a generic safety standard. It does not cover all the requirements (e.g.
guarding, interlocking or control) which are needed or required by other standards or
regulations in order to safeguard personnel from hazards other than electrical hazards. Each
type of machine has unique requirements to be accommodated to provide adequate safety.
NOTE 5 In some machines the high-voltage power supply can be produced by a step-up transformer
(autotransformer), supplied by a low-voltage system (e.g. by a LV generator).
NOTE 6 In the context of this document, the term "person" refers to any individual; "personnel" are those persons
who are assigned and instructed by the user or his agent(s) in the use and care of the machine in question.
This part of IEC 60204 specifically includes, but is not limited to, machines as defined in 3.29
(Annex A lists examples of machines whose electrical equipment can be covered by this
document).
For protection against electric shock from high-voltage equipment, this document refers to
IEC 61936-1. When it comes to low-voltage equipment, this document refers to
IEC 60204-1:2016.
NOTE 7 High- and low-voltage standards use different terms regarding protection against electric shock. Whereas
high-voltage standards use the terms “direct contact” and “indirect contact”, low-voltage standards correspondingly
use “basic protection” and “fault protection”.
Additional and special requirements can apply to the electrical equipment of machines that
– are used in the open air (i.e. outside buildings or other protective structures);
– use, process or produce potentially explosive material (e.g. paint or sawdust);
– are used in potentially explosive and/or flammable atmospheres;

IEC 60204-11:2018 © IEC 2018 – 11 –
– have special risks when producing or using certain materials;
– are used in mines.
Hazards as a result of noise and vibration are excluded from the scope of this document.
