phy sical con ections among , for ex mple,
components, dev ices, as embles, and instal ations
Connection documents are used when as emblng ,
instal ing or maintaining equipment
Connection documents shal include information
identify ing the con ection points of each con ection
and the conductor or ca les used to make the
con ections In the case of terminal con ection
documents, only one end ne d be shown
Other information ma be included as ne ded or as
a propriate, and shal be included to the extent that
is required for the intended use ofthe document
The fol owing ty pes ofinformation shal be
considered for inclusion:
— conductor or ca le ty pe information ( for
ex mple, a recog niz d ty pe desig nation,
catalog ue or p rt number, material, construction,
siz , colour of insulation, v olta e rating , n mber
of conductor , other technical d ta);
— conductor or ca le n mber or item desig nation;
— identification or representation of the
con ection points ( for ex mple, item and/ or
terminal desig nation, pictorial representations,
remote end desig nation);
— instruction for, or methods of, lay ing , routing ,
termination, at achment, twisting , s re ning ,
etc
— leng th of conductor or ca le;
— sig nal desig nation and/or tech ical d ta a out

The sy mbols for the terminals to be connected shal
be ar ang ed in a g rid format, and each shal be
identified
All of the terminal sy mbols for a sing le dev ice shal
be al g ned v ertical y [horiz ntal y ] in a sequence
that prov ides a clear presentation of the con ection
information The sequence ne d not conform to the
phy sical sequence of the terminals on the dev ice
Trang 11The columns [ rows]of terminal sy mbols thus formed
shal be ar ang ed horiz ntal y [ v erticaly ]
Each conductor shal be represented b a horiz ntal
[ v ertical] connecting lne p s ing throug h the
sy mbols for the terminals to be con ected
