Foreword
The text of the International Standard IEC 60204-1:2005, prepared by IEC TC 44, Safety of machinery –
Electrotechnical aspects, together with common modifications prepared by the Technical Committee
CENELEC TC 44X, Safety of machinery – Electrotechnical aspects, was approved by CENELEC as
EN 60204-1 on 2006-06-01.
This European Standard supersedes EN 60204-1:1997.
The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement (dop) 2007-06-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn (dow) 2009-06-01
NOTE  The application of this standard can involve the selection of components and/or parts that are to be integrated with the
electrical equipment of a machine in accordance with the instructions and/or specifications of the manufacturers of the components
and/or parts.
Also, in the context of legislative duties that are applicable to machinery manufacturers within the European Union it is important to
recognise that the safety of electrical equipment can involve the use of equipment and services provided by other parties (see 3.54).
To assist manufacturers in satisfying these duties it can be necessary for the supplier of the equipment to obtain information about
its intended use. This can be facilitated by establishing an agreement between the user and supplier on basic conditions and
additional user requirements to enable proper design, application and utilization of the electrical equipment of the machine. An
enquiry form that can be used for this purpose is provided in Annex B. Such an agreement is not intended to reduce the level of
safety of the electrical equipment provided by this standard.

Standard with agreed common modifications as given below.
COMMON MODIFICATIONS
1 Scope
Replace the sixth paragraph with:
This part of EN 60204 does not specify additional and special requirements that can apply to the electrical
equipment of machines including those that
– are intended for use in open air (i.e. outside buildings or other protective structures);
– use, process, or produce potentially explosive material (for example paint or sawdust);
– are intended for use in potentially explosive and/or flammable atmospheres;
– have special risks when producing or using certain materials;
– are intended for use in mines;
– are sewing machines, units, and systems;
NOTE 7 For sewing machines, see EN 60204-31.
– are hoisting machines.
NOTE 8 For hoisting machines, see EN 60204-32.
3 Terms and definitions
3.56 uncontrolled stop
Replace the note with:
NOTE This definition does not imply any particular state of other (for example, non-electrical) stopping devices, for example
mechanical or hydraulic brakes that are outside the scope of this standard.
4 General requirements
4.1 General
In the third paragraph delete:
– audible noise at levels that cause health problems to persons;

4.2 Selection of equipment
Replace 4.2.2 with:
4.2.2 Electrical equipment in compliance with the EN 60439 series
The electrical equipment of the machine shall satisfy the safety requirements identified by the risk
assessment of the machine. Depending upon the machine, its intended use and its electrical equipment,
the designer may select parts of the electrical equipment of the machine that are in compliance with
EN 60439-1 and, as necessary, other relevant parts of the EN 60439 series (see also Annex F).
4.4 Physical environment and operating conditions
Replace 4.4.1 with:
4.4.1 General
The electrical equipment shall be suitable for the physical environment and operating conditions of its
intended use. The requirements of 4.4.2 to 4.4.8 cover the physical environment and operating conditions
of the majority of machines covered by this part of EN 60204. When special conditions apply or the limits
specified are exceeded, an agreement between user and supplier (see 4.1) is recommended (see
Annex B).
Replace 4.4.3 with:
4.4.3 Ambient air temperature
Electrical equipment shall be capable of operating correctly in the intended ambient air temperature. The
minimum requirement for all electrical equipment is correct operation between air temperatures of +5 °C
and +40 °C. For very hot environments (for example hot climates, steel mills, paper mills) and for cold
environments, additional measures are recommended (see Annex B).
Replace 4.4.7 with:
4.4.7 Ionizing and non-ionizing radiation
When equipment is subject to radiation (for example microwave, ultraviolet, lasers, X-rays), additional
measures shall be taken to avoid malfunctioning of the equipment and accelerated deterioration of the
insulation. A special agreement is recommended between the supplier and the user (see Annex B).
Replace 4.4.8 with:
4.4.8 Vibration, shock, and bump
Undesirable effects of vibration, shock and bump (including those generated by the machine and its
associated equipment and those created by the physical environment) shall be avoided by the selection
of suitable equipment, by mounting it away from the machine, or by provision of anti-vibration mountings.
A special agreement is recommended between the supplier and the user (see Annex B).

NOTE 2 Further information on the location and actuation of devices such as those used for the prevention of unexpected start-up
is provided in EN 60447.
After the fifth paragraph, replace note 2 with:
NOTE 3 The selection of a device should take into account, for example, information derived from the risk assessment, intended
use and foreseeable misuse of the device. For example, the use of disconnectors, withdrawable fuse links or withdrawable links
located in enclosed electrical operating areas can be inappropriate for use by cleaners (see 17.2 b)12)).
9 Control circuits and control functions
9.2.6.3 Enabling control
Replace with:
Enabling control (see also 10.9) is a manually activated control function interlock that:
a) when activated allows a machine operation to be initiated by a separate start control, and
b) when de-activated
– initiates a stop function in accordance with 9.2.5.3, and
– prevents initiation of machine operation.
Enabling control shall be so arranged as to minimize the possibility of defeating, for example by requiring
the de-activation of the enabling control device before machine operation may be reinitiated. It should not
be possible to defeat the enabling function by simple means.
9.2.7.3 Stop
Replace the first paragraph with:
Cableless control stations shall include a separate and clearly identifiable means to initiate the stop
function of the machine or of all the operations that can cause a hazardous situation. The actuating
means to initiate this stop function shall not be marked or labelled as an emergency stop device
(see10.7).
