1. PURPOSE To provide standards for all electrical schematic diagrams for the Large Hadron Collider (LHC) and its detectors.
2. POLICY All electrical schematic diagrams for the LHC project shall be created with a Computer Aided Design (CAD) system, in accordance with the general quality assurance policy of the LHC project. The CAD systems used for electrical schematic diagrams prepared at CERN are AutoCAD1, the AutoCAD add-on application Alpage-Elec 2, and SEE 3000 2. All electrical schematic diagrams prepared at CERN, and referenced in a CERN contractual document, shall incorporate the appropriate CERN title block. The drawing tittle shall be written in English only or English and French. All electrical schematics diagrams shall be stored in the CERN Drawing Directory (CDD) with the relevant descriptive information and identified by a unique drawing number defined in accordance with the CERN Drawing Directory rules as described in the “CDD Manual”[ 1 ]. Diagrams may be stored as Hewlett Packard Graphic Language (HPGL) plot files and native CAD files or as HPGL plot files only. All electrical schematic diagrams shall be submitted to a review and approval process before being released as described in "Drawing Management and Control", [ 2 ]. New versions of released diagrams shall be submitted to the same review and approval process as the original diagrams.
3. SCOPE This standard is applicable to: All electrical schematic diagrams for the LHC and its detectors. This includes: !
High and low voltage distribution schematic diagrams.
!
Relay, wiring and automatism schematic diagrams.
!
Lighting, power and earth protection schematic diagrams.
!
LHC main ring magnets cabling schematic diagrams.
!
Cooling and ventilation relay and automatism diagrams.
4. RESPONSIBILITIES Managers, Supervisors and Project Engineers (PE) at CERN working on the LHC Project are responsible for: !
!
Ensuring that designers and draughtsman are aware of and understand the procedures described in the present document. Ensuring that these design standards are fully implemented in their design.

LHC-PM-QA-403.00 rev 1.0 Page 5 of 14 !
Ensuring that industrial support personnel assigned to CAD design and drafting activity is suitably trained and has been informed of CERN practices before starting work.
Every designer and draughtsman is responsible for producing diagrams in compliance with these design standards. The ST Division is responsible for the definition of equipment codes used for electrical schematic diagrams. Equipment codes for LHC equipment have to be approved by the LHC Co-ordinator for equipment codes [ 3 ]. The diagrams in the categories below are produced under the responsibility of the ST Division Electrical Engineering and Telecom group (ST/EL). !
High and low voltage distribution schematic diagrams.
!
Relay, wiring and automatism schematic diagrams.
!
Lighting, power and earth protection schematic diagrams.
!
LHC main ring magnets cabling schematic diagrams.
Cooling and ventilation relay and automatism diagrams are produced under the responsibility of the ST Division Cooling and Ventilation group (ST/CV).

6. NUM BERING SCHEMES The numbering scheme for electrical schematic diagrams is derived from the scheme in use for LHC drawings. However deviations are introduced to take into account the specific needs related to electrical diagrams.
LHC Project Document No.
LHC-PM-QA-403.00 rev 1.0 Page 7 of 14
6.1 DIAGRAMS PRODUCED BY ST/EL A deviation is introduced in the use of the sequential number which is 3 digits long instead of 4. The digit freed in this way is used for a geographical location code. The structure of the drawing number is: Pro ject code :
A project identification code. For the LHC project the code is LH C
Equipment code :
An LHC equipment code (5 chars/digits). See annex A1.
Zone
A geographical location code (1 digit)
Number :
A sequential number (3 digits).
Example: PROJECT CODE
EQUIPMENT CODE
ZONE
NUMBER
L H C E B L _ _ 5 0 1 4 Note: Equipment codes shorter than 5 chars/digits shall be completed with underscores (_).
6.2 DIAGRAMS PRODUCED BY ST/CV The position normally used for the equipment code is replaced by a 1 character system code followed by a 4 digit building number. The structure of the drawing number is: Pro ject code :
A project identification code. For the LHC project the code is LH C
Sys :
An LHC system identification code. E for electrical system.
Building
A building number (4 digits).
Number :
A sequential number (4 digits).

7.1 ST/EL ELECTRICAL DIAGRAMS A plot file in HPGL2 format is prepared and placed in a sub-directory of the directory SRV4_DIV\drawings\DRAWINGS\ELEC\HPGL\. This sub-directory, and the plot file it contains, are named in accordance with the following convention: Sub-directory name
DOPRJ
File name
EQUIP3N.plt
where:

Example: The plot file of the drawing LHCEBL___5004 is named EBL5004.plt and stored in the sub-directory SRV4_DIV\drawings\DRAWINGS\ELEC\HPGL\77LHC\. Only the last version of the plot file is stored in this directory.
7.2 ST/CV ELECTRICAL DIAGRAMS A plot file in HPGL2 format is prepared; it is named and stored following the convention described in section 12.1 with the exception of the file extension which is PLT instead of DWG.
8. HIGH AND LOW VOLTAGE DISTRIBUTION UN IFI LAR DIAGRAMS High and low voltage distribution single line diagrams are prepared with the CAD system Alpage Elec which will be replaced by SEE 3000 in the future.

10. LIGHTING, POW ER AND EARTH PR OTECTION DI AGRAMS Lighting, power and earth protection schematic diagrams are combinations of an electrical schematic diagram and an equipment installation layout. They are prepared with AutoCAD. The parts list of equipment is prepared with the help of a CERN developed AutoCAD application named ATT_TAB. This application is described in the document “Etude et développement d’applications dans l’environnement DAO AutoCAD pour l’aide à la gestion d’études électriques" written by A. Croissant in 1992. They shall be prepared in accordance to the International Electrotechnical Commission (IEC) 60617 standards, [ 8 ], as well as to CERN Safety Instructions IS23, [ 6 ] and IS24, [ 7 ]. The following rules shall be respected when preparing a drawing: !
The schematic part is drawn on the layer "SCHEMA".
!
The installation layout part is drawn on the layer "IMP".
!
They are drawn using the symbols library available on the NICE server I:\SRV4_DIV\drawings\DRAWINGS\ELEC\BE_LHC\STANDARD\WB
10.1 FILE NAMING CONVENTION The native CAD files are stored on the NICE server SRV4_DIV\drawings\, in the directory DRAWINGS\ELEC\. A sub-directory is created for each set of diagrams. This sub-directory, and the drawing files it contains, are named in accordance with the following conventions: Sub-directory name:
DOPRJ
File name:
EQUIPNUM.DWG
where: DOPRJ:
Design office code (2 digits) concatenated with a project code (3chars)
EQUIP:
Equipment code (5 chars/digits)
