IEC 60204-11:2000 pdf download-Safety of machinery – Electrical equipment of machines – Part 11: Requirements for HV equipment for voltages above 1 000 V a.c. or 1 500 V d.c. and not exceeding 36 kV.
3.24 live part conductor or conductive part intended to be energized in normal operation, including a neutral conductor, but by convention not a PEN conductor or PEM conductor or PEL conductor NOTE This concept does not necessarily imply a risk of electric shock. [IEV 195-02-19] 3.25 machine bonding conductor conductor connecting the machine equipotential bonding to the earthing system NOTE This is an earthing conductor as defined in IEV 826-04-07 and used in HD 637. 3.26 machinery (machine) a) assembly of linked parts or components, at least one of which moves, with the appropriate machine actuators, control and power circuits, etc., joined together for a specific appli- cation, in particular for the processing, treatment, moving or packaging of a material b) assembly of machines which, in order to achieve one and the same end, are arranged and controlled so that they function as an integral whole c) interchangeable equipment modifying the function of a machine, which is placed on the market (supplied) for the purpose of being assembled with a machine or a series of different machines or with a tractor by the operator himself insofar as this equipment is not a spare part or tool 3.27 marking signs or inscriptions for the identification of the type of a component or device attached by the manufacturer of the component or device 3.28 neutral conductor conductor electrically connected to the neutral point and capable of contributing to the distribution of electric energy [IEV 195-02-06] 3.29 obstacle part preventing unintentional direct contact, but not preventing direct contact by deliberate action [IEV 826-03-14] 3.30 overcurrent current exceeding the rated value. For conductors, the rated value is the current-carrying capacity [IEV 826-05-06] 3.31 overload (of a circuit) time/current relationship in a circuit which is in excess of the rated full load of the circuit when the circuit is not under a fault condition NOTE “Overload” should not be used as a synonym for overcurrent.
