bi-colour combination green-and-yellow.
For cables and cords having more than 5 conductors, each conductor shall be identified by colours or by
numerals according to EN 60446. Conductors identified by numerals and used as a protective conductor or
neutral conductor shall be marked green-and-yellow or blue, respectively, at each termination.
514.3.Z3 Identification of single-core cables and insulated conductors
Line conductors shall be identified throughout their length by the colours brown or black or grey. The use of
one of these colours for all of the line conductors in a circuit is permitted.
Sheathed single-core cables and insulated conductors in compliance with their relevant standard which are
not available with green-and-yellow or blue insulation, e.g. in case of large cross-sectional areas, larger than
16 mm², may be used as:
- protective conductor if a green-and-yellow marking is provided at each termination;
- PEN conductor if a green-and-yellow marking and a blue marking is provided at each termination;
- neutral conductor if a blue marking is provided at each termination.
514.3.Z4 Use of a blue conductor for certain applications
For certain applications, provided that confusion is not possible and there is no neutral conductor, a blue
conductor may be used as a line conductor or for any other purpose, except as a protective conductor.
NOTE This could be the case, for example, in part of a circuit between a switch and current-using equipment.
514.3.Z5 Omission of identification
Identification by colour or marking is not required
- for concentric conductors of cables,
- for metal sheath or armour, of cables, that is used as a protective conductor,
- for bare conductors in cases where a permanent identification is not possible due to the external
influences, e.g. aggressive atmosphere and pollution,
- for metal structural parts of the structure or extraneous conductive parts used as protective conductors,
- for bare overhead wiring.
Identification by colour is not required for the conductors of flat flexible cables without a sheath or cables
having insulation materials which cannot be identified by colour, for example mineral insulated cables. For
these cables the cores used as protective conductors or PEN or neutral conductors shall be provided with
markings of the relevant colour (see 514.3.Z3, last paragraph) at their termination

External influences
ZA.1 (512.2) External influences
ZA.1.1 (512.2.1) Electrical equipment shall be selected and erected in accordance with the requirements of
Table ZA.1, which indicates the characteristics of equipment necessary according to the external influences
to which the equipment may be subjected.
Equipment characteristics shall be determined either by a degree of protection or by conformity to tests.
ZA.1.2 (512.2.2) If the equipment does not, by its construction, have the characteristics relevant to the
external influences of its location, it may nevertheless be used on condition that it is provided with
appropriate additional protection in the erection of the installation. Such protection shall not adversely affect
the operation of the equipment thus protected.
ZA.1.3 (512.2.3) When different external influences occur simultaneously, they may have independent or
mutual effect and the degree of protection shall be provided accordingly.
ZA.1.4 (512.2.4) The selection of equipment according to external influences is necessary not only for
proper functioning, but also to ensure the reliability of the measures of protection for safety complying with
the rules of IEC 60364 generally. Measures of protection afforded by the construction of equipment are valid
only for the given conditions of external influence if the corresponding equipment specification tests are
made in these conditions of external influence.
NOTE 1 For the purpose of this standard, the following classes of external influences are conventionally regarded as normal:
AA Ambient temperature AA4
AB Atmospheric humidity AB4
Other environmental conditions XX1 of each parameter
(AC to AR)
Utilisation and construction XX1 of each parameter, except
of building (B and C) XX2 for the parameter BC
NOTE 2 The word “normal” appearing in the third column of the table signifies that the requirement must generally satisfy applicable

A Environmental conditions
AA Ambient temperature
The ambient temperature is that of the ambient air
where the equipment is to be installed.
It is assumed that the ambient temperature includes
the effects of other equipment installed in the same
location.
The ambient temperature to be considered for the
equipment is the temperature at the place where the
equipment is to be installed resulting from the
influence of all other equipment in the same location,
when operating, not taking into account the thermal
contribution of the equipment to be installed.
Lower and upper limits of ranges of ambient
temperature:
AA1 –60 °C +5 °C Includes temperature range of
IEC 60721-3-3, class 3K8, with
high air temperature restricted
to +5 °C. Part of temperature
range of IEC 60721-3-4, class
4K4, with low air temperature
restricted to –60 °C and high air
temperature restricted
to +5 °C

range of EN 60721-3-4, class
4K1, with high air temperature
restricted to +5 °C
AA4 –5 °C +40 °C Normal (in certain cases Part of the temperature range
special precautions may be of EN 60721-3-3, class 3K5, with
necessary) the high air temperatures
restricted to +40 °C
AA5 +5°C +40 °C Normal
Identical to temperature range
of EN 60721-3-3, class 3K3

May necessitate certain supplementary precautions (e.g. special lubrication).
b
This means that ordinary equipment will operate safely under the described external influences.
c
This means that special arrangements should be made, for example, between the designer of the installation and the
equipment manufacturer, e.g. for specially designed equipment.

Vsak del opreme je treba izbrati in namestiti v skladu s pravili, določenimi v naslednjih točkah tega
dela SIST HD 384/60364, in z ustreznimi pravili v drugih delih skupine HD 384/60364.
511 Skladnost s standardi
511.1 Vsak del opreme mora biti skladen z zahtevami ustreznih evropskih standardov (EN),
harmoniziranih dokumentov (HD) ali nacionalnih standardov, ki uvajajo HD. Če EN ali HD ni, mora biti
naprava skladna z zahtevami ustreznih nacionalnih standardov. V vseh drugih primerih naj se
upoštevajo ustrezni standardi IEC ali nacionalni standardi druge države.
511.2 Kjer ni ustreznih standardov, je treba del opreme izbrati po posebnem dogovoru med osebo, ki
je določila inštalacijo, in inštalaterjem.
512 Obratovalni pogoji in zunanji vplivi
512.1 Obratovalni pogoji
512.1.1 Napetost
Naprava mora biti ustrezna za nazivno napetost (efektivna vrednost za izmenične tokokroge) inštalacije.
Če je v inštalacijah IT nevtralni vodnik položen, je treba napravo, priključeno med fazo in nevtralni
vodnik, izolirati za napetost med fazami.
OPOMBA: Za posebne naprave je morda nujno upoštevati najvišjo in/ali najnižjo napetost, ki se lahko pojavi pri normalni uporabi.
512.1.2 Tok
Napravo je treba izbrati za načrtovani tok (efektivna vrednost za izmenične tokokroge), ki ga mora
prenašati v normalnem obratovanju.
Naprava mora biti sposobna prenašati tudi tok, ki je možen v nenormalnih pogojih, za toliko časa, kot
določajo karakteristike zaščitnih naprav.
512.1.3 Frekvenca
Če ima frekvenca vpliv na karakteristike naprav, mora nazivna frekvenca naprave ustrezati frekvenci
toka v obravnavanem tokokrogu.
512.1.4 Moč
Naprava, izbrana glede na njene močnostne karakteristike, mora ustrezati normalnim obratovalnim
pogojem ob upoštevanju faktorja obremenitve.

512.1.5 Združljivost
Če med namestitvijo ni drugih primernih varnostnih ukrepov, je treba vse naprave izbrati tako, da ne
povzročajo škodljivih učinkov na drugih napravah in ne slabšajo napajanja med normalno uporabo,
vključno pri vklopu in izklopu.
OPOMBA: Informacije o parametrih, ki jih je treba upoštevati, so dane v poglavju 33 in točki 444.
512.1.Z1 Odpornost proti napetostnim udarom
Napravo je treba izbrati tako, da je nazivna odpornost proti napetostnim udarom najmanj enaka
predvideni prenapetosti v točki inštalacije, kot je opredeljeno v točki 443.
512.2 Zunanji vplivi
(Glej dodatek ZA.)
513 Dostopnost
513.1 Splošno
Vse naprave, vključno ožičenje, je treba prirediti tako, da to olajša njihovo obratovanje, nadzor,
vzdrževanje in dostop do priključkov. Te olajšave se ne smejo pomembno poslabšati zaradi montaže
opreme v ohišja ali v prostore.
514 Identifikacija
514.1 Splošno
Predvideti je treba nalepke, napisne tablice in druge primerne načine označevanja, ki identificirajo
namen stikalne in krmilne naprave, razen če ni možnosti zamenjave.
Kjer operater ne more opazovati delovanja stikalne in krmilne naprave in kjer to lahko povzroči
nevarnost, je treba namestiti primerno oznako na tako mesto, da je vidna operaterju, skladno z EN
60073 in EN 60477.
514.2 Inštalacijski sistem
Inštalacijo je treba razmestiti ali označiti tako, da jo je mogoče prepoznati pri pregledu, preskušanju,
popravilu ali predelavi.
514.3 Identifikacija nevtralnih in zaščitnih vodnikov
514.3.1 Splošno
Če v 514.3.1.Z1 do 514.3.Z5 ni določeno drugače, mora biti označevanje vodnikov skladno z
EN 60446, Temeljna in varnostna načela za vmesnik človek-stroj, označevanje in identifikacija –
Identifikacija vodnikov z barvami ali številkami.
514.3.1.Z1 Nevtralni ali skupni vodnik
Nevtralni ali skupni vodnik mora biti označen z modro barvo po vsej dolžini.
