This part of IEC 60204 applies to
electrical, electronic and programmable electronic equipment and
systems to machines not portable by hand while working, including a
group of machines working together in a co-ordinated manner.
NOTE 1
This part of
IEC 60204 is an application
standard and is not intended to limit or inhibit technological
advancement.
NOTE 2
In this part of
IEC 60204 , the term “
electrical” includes electrical, electronic and programmable
electronic matters (i.e. “electrical equipment” means electrical,
electronic and programmable electronic equipment).
NOTE 3
In the context of this part of
IEC 60204 , the term “person”
refers to any individual and includes those persons who are
assigned and instructed by the user or his agent(s) in the use
and care of the machine in question.
The equipment covered by this part of IEC 60204 commences at the
point of connection of the supply to the electrical equipment of
the machine (see 5.1).
NOTE 4
The requirements for the electrical supply installation are
given in the
IEC 60364 series.
This part of IEC 60204 is applicable to the
electrical equipment or parts of the electrical equipment that
operate with nominal supply voltages not exceeding 1 000 V for
alternating current (AC) and not exceeding 1 500 V for direct
current (DC), and with nominal supply frequencies not exceeding
200 Hz.
NOTE 5
Information on electrical equipment or parts of the electrical
equipment that operate with higher nominal supply voltages can be
found in
IEC 60204?11 .
This part of IEC 60204 does not cover all
the requirements (for example guarding, interlocking, or control)
that are needed or required by other standards or regulations in
order to protect persons from hazards other than electrical
hazards. Each type of machine has unique requirements to be
accommodated to provide adequate safety.
This part of IEC 60204 specifically
includes, but is not limited to, the electrical equipment of
machines as defined in 3.1.40.
NOTE 6
Annex C lists examples of machines
whose electrical equipment can be covered by this part of
IEC 60204 .
This part of IEC 60204 does not specify
additional and special requirements that can apply to the
electrical equipment of machines that, for example:
-
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 (which are covered
by
IEC 60204?31 );
-
are hoisting machines (which are covered by
IEC 60204?32 );
-
are semiconductor fabrication equipment (which are covered
by
IEC 60204?33 ).
Power circuits where electrical energy is directly used as a
working tool are excluded from this part of IEC 60204 .
