2 Definitions

For the purpose of this p rt of IEC 10 2, the

fol owing definitions a ply

instalation

a) Activ ities of ar ang ing faci ities for electrical

equipment and of placing and inter on ecting it

on site with the purpose of making it rea y for

fu ctioning tog ether

b) Result of these activ ities, e.g the l g hting

sy stem of a house

N T 1 Instalation ma b p rt of the man facturing roces

of pre-as embled u its Documents for these activities are not the

subject of this stan ard

N T 2 The term “instalation” is used for the set-up of

computer software Documents for this activity are not the

subject of this stan ard

N T 3 The term “instalation” is often used for an o ject

( e.g , the lghting system of a house)

instalation phase

period in the l fetime of a plant or sy stem betwe n

delv ery and commis ioning of electrical equipment

during which the instal ation work ( erecting ,

instal ng , con ecting , etc.) is done ( se Fig ure 1)

N T I is considered, as far as the pre aration of documents

is concerned, that the lfetime b gins when the plant or sy stem is

desig ned an plan ed

instal ation docum ents

documents mainly sup orting the activ ities in

relation to the instalation phase of a project

further definitions of terms used in this stand rd

are presented in IEC 10 2-1

3 Electrical instal ations, docum ents

and inform ation

3.1 K inds ofele trical instal ations

Electrical instal ations can be div ided into sep rate

sy stems, e.g lg hting , power sup ly , etc The

sy stems can be instaled in diferent objects l ke

ships, buiding s, mines, etc ( se Ta le 1) The rules

and principles presented in this stand rd a ply

b sical y to al sy stems and are not restricted to any

object Specific requirements for the diferent fields

of tech olog y or diferent branches are not treated

NOT The definition of kin s of electrical instalations or

systems is not the subject of this stan ard

Ta le 1shows ex mples of sy stems and objects Any

combination of these is pos ible The let er in the

ta le represent ex mples of diferent instalation

projects

Project A: Telecommu ication and security

sy stem in a commer ial buiding

Project B: Power and lg ht sy stem in the same

commer ial bui ding as project A

Project C: Alarm sy stem in a mine

Project D: Control and d ta sy stem and

air-conditioning sy stem in an air raft

Each sy stem within one instalation project should

normal y be documented sep rately , taking into

ac ount the complexity of the instal ation Diferent

sy stems ma hav e diferent requirements

concerning the information neces ary for their

instal ation A combined presentation shal only be

used if the diferent sy stems are clearly

disting uisha le f om one another

Fig ure 1 — Perio s in the l fetim e of a plant or system

Table 1 — Ex m ples of systems and o je ts

3.2 Instal ation docum ents

Instalation documents ma serv e as a b sis for:

— instal ng conduits, ducts, racks, etc

— lay ing conductor and ca les;

— placing equipment;

— inter on ecting equipment;

— inspecting the instal ation;

— etc

They ma also serv e as a b sis for activ ities outside

the instal ation phase, e.g :

— specification and calculation of material and

work;

— desig n of equipment sup orts

( e.g fou d tions);

— desig n of other sy stems

In practice sup lementary documents ma be

required for such purposes as manufacturing ,

operation or maintenance, but they also contain

information of importance for instal ation

Function-oriented diag rams and con ection

diag rams, ta les and lsts are cov ered in

IEC 10 2-2 and IEC10 2-3 Parts l sts are under

consideration as a sep rate p rt of this stand rd

Rules for the prep ration of location documents are

presented in clause 4 of this stand rd

N T Location documents ma b combined with other

documents,e.g fu ction-oriented or con ection documents

W hich kinds of document are to be prep red and

sup led depends on the information required for

the specific task or instalation project ac ording to

its siz and complexity This is subject to ag re ment

betwe n the p rties inv olv ed

3.3 Inform ation for instal ation purposes

For each instalation activ ity a certain amou t of

information is required This shal be prov ided b

diferent kinds of instal ation documents and

sup lementary documents to the extent ag re d

upon, e.g in a contract

The amou t of information to be presented in the

documents ma difer considera ly ac ording to the

complexity of the sy stem to be instal ed, the

av ai a i ity of esta l shed rules, reg ulations,

stand rds, customer stipulations, etc or the ski of

the instal ation per on el

Residential bui ding s

Ta le 2 shows ex mples ofinformation ne ded for

diferent activ ities, and presents those kinds of

documents in which this information ma be g iv en

NOT Rules an guidelnes for commu ication b twe n p rties

inv olv d in a project concerning documentation for plants an

systems,inclu ing the content of information re uired in

documents, are u der consideration

The ta le ma be used as a checklst when

contractor are neg otiating a out the documents

neces ary for a certain instal ation project A certain

4 Comm on rules for presentation of

location docum ents

4.1 General

Location documents shal be prep red in ac ord nce

with the rules in IEC 10 2-1 and with the rules

g iv en in this p rt of IEC 10 2

They mainly des ribe the relativ e or a solute

position and/or dimensions of objects by :

— simplfied sha es of objects;

— main dimensions of objects and/ or distances

betwe n them;

— sy mbols representing objects

Information on aspects other than “ location” ma be

included if this is ag re d The location information

shal be presented tog ether with neces ary

information a out the sur ou ding s in which the

electrical objects are ( to be) located

4.2 Basic docum ents

It is as umed in this stand rd that the b sic

documents are prep red ac ording to ISO stand rds

concerning formats, l nes, let ering , etc

( se IEC 10 2-1) Basic documents are for ex mple

ar hitectural documents, lands a e ma s, site

plans, etc They may , if ag re d, be drawn

isometricaly or in per pectiv e

NOT Basic documents are mostly pre ared b

non-electrotech ical p rties lke oficial authorities, ar hitects’ or

civ il engine r ’ drawing ofices, normaly folowing the rules of

ISO stan ards

Requirements for the content of information in b sic

documents are subject to ag re ment betwe n the

p rties inv olv ed in an instal ation project The

document( s) should be del v ered for electrical desig n

without information a out items of non-electrical

instal ations, furniture, decorativ e elements etc I

such information is neces ary for the plan ing of

electrical instalations, this should be prov ided in

sep rate b sic documents

NOT The use of la er tech ique ( se 4.3) ma b

adv nta e us when computer aided design systems

( CAD systems) are a pled

For p per-b sed documents, methods for improv ed

contrasting ma be used lke g rey ish in ing or a

diferent colour for the b sic detai s These methods

shal only be used in so far as they do not afect the

rea a i ity of the final document, for ex mple after

copy ing or printing

4.3 Guidel nes when using CAD systems

W here a CAD sy stem al ows it, diferent sy stems

should be kept sep rately , each kind being placed in

its own lay er but with the pos ibi ty to combine the

diferent lay er The b sis for al lay er shal be a

b sic document ac ording to 4.2

Electrical instal ation detais should not be mixed

with detai s of other sy stems ( se 4.4); howev er the

position of non-electrical equipment, for instance

water-pipes, should be considered

For ex mple the orig inal simple ar hitectural

drawing is the b sic lay er The ca le routing les in

another lay er, the l g hting sy stem in a third and the

ar ang ement of switchg ear cubicles and other

electrical material in a fourth lay er ( se Fig ure 2)

NOT The use of la er a ples to two-dimensional

re resentation only

4.4 La out

Location documents shal hav e a clear lay out to

faci tate rea ing and u der tanding of the

contained information

Non-electrical objects shal only be shown if the

information is important for the u der tanding of

the document and for the proper erection of the

electrical instal ation This is p rticularly

important if there is a tendency to ov er rowd the

document with u neces ary detais

I non-electrical objects are shown they shal be

presented in such a wa that they are clearly

disting uisha le fom the electrical objects

Fig ure 2 — Ex m ple ofthe use of la er te hnique

Ov er rowding of the documents shal be av oided b

the choice of a propriate s ales and representation

tech iques ( se IEC 10 2-1 and 4.5.2 of this

stand rd) W rit en information shal be placed

where it do s not conflct with other information,

e.g in a fixed p rt of al the documents

( prefera ly at the rig ht-hand side a ov e the title

block)

I neces ary information is contained in other

documents, e.g in an instal ation des ription,

reference to these shal be g iv en on the document

4.5 Gra hical representation of components

and conne tions

4.5.1 Repre ent at ion o component s

4.5.1.1 Electr ica l components

Electrical components are normal y represented b

their simpl fied sha e showing the main outl nes, or

b a g ra hical sy mbol Sy mbols for use on

instalation documents shal be chosen fom

IEC 617

Mou ting methods and/or directions shal be stated

in the document I sing le items or components

require diferent mou ting methods or directions,

this ma be specified b let er a jacent to the

sy mbols, for ex mple:

Other let er ma be defined as required

The let er ma be combined and shal be ex lained

on the document or in sup orting documentation

N T 1 For wal mou ting of lamps a symb l is av aia le

(symb l 1 -1 -0 in IE 6 7)

N T 2 A more comprehensiv e let er code for factory-buit

wiring systems is u der consideration

In more compl cated cases, a sep rate i ustration

( smal sketch) and/or des ription ma be neces ary

The presentation of sy mbols shal be in ac ord nce

with IEC 10 2-1 ( for sy mbol siz refer to 4.4.3 of

IEC10 2-1)

Major electrical components ma be represented b

their simpl fied outl ne if they do not hav e a

stand rdised sy mbol or if the sy mbol would be

impractical to use

4.5.1.2 Non-electr ica l components

I sy mbols for non-electrical components are

required they shal be chosen f om the relev ant ISO

publcations

4.5.1.3 Exa mpl es f r the us o symbol s on

insta lla tion d ia gr a ms

In Ta le 3 some ex mples are g iv en for the

recommended use of sy mbols, taken fom

IEC617-1 , on diag rams They ma also be used the

same wa on instal ation drawing swithout

con ecting l nes

H = horiz ntal ( components mou ted side

Ta le 3 — Exam ples for the use of sym bols

4.5.2 Conne t ing l ine , r ut ing

I it is required to show conductor they shal be

drawn in sing le- ne representation as des ribed in

IEC 617 and in IEC 10 2-1 Multi ine

representation should only be used if it is neces ary

to ex lain complcated con ection detais

The con ecting lnes shal be clearly disting uisha le

f om the l nes showing the lands a e or structural

and ar hitectural detais For ex mple l ne

thick es es or inking diferent fom those on the

b sic document ma be used Other methods for this

purpose are the use of hatching or sha ing of wals

For an ex mple se Fig ure A.2

W here many p ralel con ecting lnes tend to

ov er rowd the diag ram the use of simpl fication

tech iques l ke bu dlng ( des ribed in 4.4.7.2 of

IEC10 2-1), or inter uption of l nes ( des ribed

in4.4.6 of IEC 10 2-1) is recommended

Another method of showing that con ections exist is

g iv en b the use of a propriate item desig nations

( se 4.5.3)

4.5.3 Us o referenc d esignat ions

I an item desig nation sy stem is required — mostly

for complex instal ations — a reference desig nation

shal be shown a jacent to each sy mbol in a drawing

or diag ram The reference desig nation shal be in

ac ord nce with IEC13 6 ( Se also an ex A.)

4.5.4 Te hnical dat a

Technical d ta ( rating s) of indiv idual components

shal normaly be stated in p rts lsts For clarity or

to disting uish items difering fom the majority of

items, a characteristic v alue ma also be shown

a jacent to the sy mbol and the item desig nation on

the document:

As an exception to IEC 10 2-1 the d ta ma be

placed where the lay out of the drawing permits

( se Fig ure 4c)

5 Difer nt kinds oflocation

docum ents

Location des ribing documents are diferentiated as

shown in the tre structure presented in Fig ure 3

The word “ bui ding ” is used here as a g eneral term

for al containments enclosing tech ical plants or

sy stems, e.g houses, ships, air raft, ofshore

platforms, etc

5.1 Requirem ents on basic documents

The b sis for al instal ation documents shal be

lay out documents ( term and definition ac ording to

ISO1020 -1) l ke a site plan, a bui ding drawing

etc These documents are mostly prep red b

p rties outside the electrotech ical field They shal

fulfi requirements on information neces ary for the

plan ing of electrical instalations as fol ows

5.1.1 Requirement s on sit e pl ans

Site plans ( se IEC 10 2-1) are often the b sis for

instalation documents showing the location of

electrical equipment on a site

Site plans shal be drawn to s ale, which shal be

clearly stated, u les otherwise ag re d

Site plans shal show the form of the lands a e or

the buiding site tog ether with al neces ary

information for the plan ing of electrical

instalations and for locating electrical equipment

The plan shal hav e g eog ra hical orientation points,

north-direction indicator, the location and outlne of

bui ding s, trafic areas, serv ice networks, ac es

faci ties, major items and site bou d ries

Adjacent faci ities l ke power lnes or bridg es shal

be shown if they influence the instal ations on the

area in any sig nificant way

5.1.2 Requirement s on buil d ing drawings

Buiding drawing s are mostly the b sis for

instalation documents des ribing the location of

electrical equipment in a bui ding

Buiding drawing s for electrical instal ation

purposes shal be drawn to s ale, which shal be

clearly stated, u les otherwise ag re d

Buiding drawing s shal show:

— outlnes and constructional detai s of ro ms,

ca ins, cor idor , opening s, windows, do r , etc

in plans and sectional v iews;

— buiding obstructions e.g structural ste l

beams and stanchions;

— the loa ca acity of flo r or decks if required

and any lmitations on cut ing , dri ing or

welding ;

— ro m for special instal ations l ke lfts, c anes,

heating , co lng and v enti ation sy stems;

— other equipment that is of importance for the

electrical instal ation;

— hazardous areas ( if any );

— earthing points

5.1.3 Requirement s on drawings o me hanical

component s

Lay out drawing s of mechanical components are

used as input information for positioning and

con ecting electrical components They shal
