Introduction
The requirements of this part of HD 60364 modify or replace certain of the general requirements of
HD 60364.
The clause numbering of Part 7-715 follows the pattern and corresponding references of HD 60364.
The numbers following the particular number of Part 7-715 are those of the corresponding parts or
clauses of HD 60364.
The absence of reference to a part or a clause means that the general requirements of HD 60364 are
applicable.
Numbering in parenthesis corresponds to the numbering of the “non restructured” IEC 60364 (HD 384)
dated before 2002.
715 Extra-low-voltage lighting installations
715.1 Scope
The particular requirements of this part apply to extra-low-voltage lighting installations supplied from
sources with a maximum rated voltage of 50 V a.c. or 120 V d.c.
NOTE 1 For the definition of an extra-low-voltage lighting system, see EN 60598-1.
NOTE 2 AC voltages are given as r.m.s. values.
NOTE Z1 The maximum d.c. value for SELV luminaires is under consideration.
715.2 Normative references
See Annex ZA.
715.411 Protection against both direct and indirect contact
715.411.1 For extra-low-voltage lighting installations only SELV shall be applied. Where bare
conductors are used (see 715.521.7), the maximum voltage shall be 25 V a.c. or 60 V d.c. according to
411.1.4.3 of HD 384.4.41.
715.411.1.2 Safety isolating transformers shall conform with EN 61558-2-6.

Parallel operation of transformers in the secondary circuit is allowed only if they are also paralleled in the
primary circuit and the transformers have identical electrical characteristics.
Safety isolating converters shall conform to EN 61347-2-2, Annex I.
Parallel operation of converters is not accepted.

715.43 Protection against overcurrent
The SELV circuit shall be protected against overcurrent either by a common protective device or a
protective device for each SELV circuit, in accordance with the requirements of HD 384.4.43.
NOTE 1 When selecting the protective device for the primary circuit, account should be taken of the magnetising current of the
transformer.
Self-resetting overcurrent protective devices shall only be required for transformers up to 50 VA.
NOTE 2 Overcurrent protection may be provided by a protective device complying with the requirements of 715.482.5.2.
715.46 (715.536) Isolation and switching
715.462.5 Where transformers are operated in parallel the primary circuit shall be permanently
connected to a common isolating device.
715.482 (715.422) Protection against fire
715.482.2 (715.422.3) Nature of processed or stored materials
715.482.2.3 (422.3.3) The manufacturer’s installation instructions shall be followed, including those
relating to mounting on flammable or non-flammable surfaces. See also HD 60364-5-559.
NOTE Z1 Luminaires suitable for direct mounting on normally flammable surfaces are marked with the symbol .
715.482.4 (422.5) Fire risk of transformers/converters
715.482.4.1 (422.5.1) Transformers shall be either:
- protected on the primary side by the protective device required in 715.482.5.2; or
- short-circuit proof transformers (both inherently and non-inherently proof), see Annex A for the
symbol.
715.482.4.2 Electronic converters shall comply with EN 61347-2-2, and with the requirements of
EN 60598-2-23.
NOTE It is recommended that converters marked with the symbol are used. See Annex A for the symbol.
