BS EN 60204-1:1993

Specifies general requirements for an individual machine as well as a group of machines operating in a coordinated manner for compliance with the Essential Safety Requirements in annex 1 of Council Directive 89/392/EEC on machines. Fulfils the requirements of the Low Voltage Directive 73/23/EEC.

This Part of EN 60204 applies to the application of electrical and electronic equipment and systems to machines including a group of machines working together in a coordinated manner but excluding higher level systems aspects (i.e. communications between systems).

NOTE 1 In this Part, the term electrical includes both electrical and electronic matters (e.g. electrical equipment means both the electrical and electronic equipment).

NOTE 2 Not used.

NOTE 3 In the context of this Part, 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 integrated manufacturing system in question.

The equipment covered by this Part commences at the point of connection of the supply to the electrical equipment of the machine (see 5.1). This Part is applicable to equipment or parts of equipment which operate with nominal supply voltages not exceeding 1000 V a.c. or 1500 V d.c. between lines and nominal frequencies not exceeding 200 Hz. For higher voltages or frequencies, special requirements may be needed.

NOTE 4 These special requirements are under consideration for a further Part of EN 60204.

This Part is a basic 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 persons from hazards other than electrical. Each type of machine has unique requirements which shall be accommodated to provide adequate safety.

This Part specifically includes, but is not limited to, the electrical equipment of industrial machines as defined in 3.28 (annex A lists examples of machines whose electrical equipment may be covered by this standard).

Also applicable is electrical equipment of machines for assembling, material handling (e.g. conveyors) and inspection, where associated with machines referred to above.

Additional and special requirements can apply to the electrical equipment of machines which:

• are used in open air (i.e outside buildings or other protective structures);

• use, process or produce explosive material (e.g. paint or sawdust);

• are used in explosive and/or flammable atmospheres;

• give rise to special risks when producing certain materials;

• are used in mines;

• are sewing machines, units and systems (see EN 60204-3-1).

Excluded from this Part are:

• power circuits where electrical energy is directly used as a working tool.
