BS EN 60204-11:2000 Safety of machinery - Electrical equipment of machines - Requirements for HV equipment for voltages above 1000 V a.c. or 1500 V d.c. and not exceeding 36 kV
IEC 60204 applies to the electrical and electronic equipment and systems of machines,
including a group of machines working together in a coordinated manner, but excluding higher
level system aspects (i.e. communications between systems).
This part of IEC 60204 is applicable to equipment, or parts of equipment, which operate with
nominal supply voltages above 1 000 V a.c. or 1 500 V d.c. and not exceeding 36 kV a.c. or
d.c. with nominal frequencies not exceeding 200 Hz. For higher voltages or frequencies,
special requirements may be needed.
In this standard, the term HV equipment also covers the LV equipment forming an integral
part of the equipment operating at high voltage. The requirements in this standard primarily
cover the parts operating at high voltage except where explicitly stated otherwise. Reference
is made to IEC 60204-1 for those requirements which also apply to HV equipment.
The electrical 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).
This part of IEC 60204 is an application standard and is not intended to limit or inhibit
technological advancement. 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.
This part of IEC 60204 specifically includes, but is not limited to, machines as defined in 3.26
(annex A lists examples of machines whose electrical equipment may be covered by this
standard).
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;
– have special risks when producing or using certain materials;
– are used in mines.
Power circuits where electrical energy is directly used as a working tool are excluded from
this part of IEC 60204.
