2.1 Definitions relating to ratings, voltages, currents, frequencies, and wattages
Replace, on page 21, after definition 2.1.3, the following definitions:
2.1.4
extra-low voltage (ELV)
nominal voltage not exceeding 50 V between conductors and between conductors and earth,
or for three-phase connection not exceeding 50 V between line conductors and 29 V between
line conductors and neutral
NOTE 1 These values were derived from IEC 60335-1, definition 3.4.1.
NOTE 2 In this standard ELV-levels for use in a specific application as specified in the relevant application
standard may be declared for controls used in or with such applications for environmental conditions as specified
by the application standard.
2.1.5
safety extra-low voltage (SELV)
nominal voltage for use in a SELV-system or PELV-system between conductors and between
conductors and earth, not exceeding 42 V between conductors, or in the case of three-phase
circuits, not exceeding 24 V between conductors and neutral, the no-load voltage of the circuit
not exceeding 50 V and 29 V, respectively, and which when obtained from higher voltage is
provided by a safety isolating transformer or a converter with separate windings providing
equivalent insulation as stated in IEC 61558-2-6 and IEC 61558-2-17
The voltage limits are based on the assumption that the safety isolating transformer is supplied at its rated voltage.
NOTE In Canada and the USA, the limit for safety extra-low voltage is 30 V.

2.7.15
equipotential bonding
provision of electric connections between conductive parts, intended to achieve
equipotentiality
[IEV 195-01-10]
The effectiveness of the equipotential bonding depends on the frequency of the current in the bonding.
Equipotential bonding is used to connect any conductive part of a building not forming part of the electrical
installation and liable to introduce an electrical potential, generally the electric potential of the local earth
(extraneous-conductive part) and any conductive part of controls or equipment or components in the installation
which can be touched and which is not normally live but which can become live when basic insulation fails
(exposed-conductive part) to a main equipotential bonding terminal in the form of a bar, in order to bring these
parts to the same potential. Parts to be connected to the equipotential bonding system include e.g. protective
conductors, PE conductors, PEN conductors, earthing conductors, protective earthing terminals of controls or
equipment, all conductive parts in a building, e.g. metal tubing for water (drinking and waste), metallic bathtubs,
the central heating system piping, any internal gas tubing (which is also required to be isolated from external gas
tubing), earth connectors for antennas and telecommunication systems, all metal parts of the building used for
construction like mats and iron, and conductors for lightning protection and depending on the installation system,
the earth electrode. Requirements for equipotential bonding can be found in the IEC standards for the installation
of buildings. These may be relevant for the installation of controls which consist of several component-parts (e.g.
sensors, actors, central control element, interface elements) connected in parallel to or via the fixed installation of
the building.

protective-equipotential-bonding
