Can anyone help me. I have been asked to produce a set of schematics to IEC standards. Can anyone provide me with a typical example. Many thanks.

Oh, if it were that simple.


For starters, you will need to install the IEC Menus into ACE (I am assuming that you did not do it during the installation).


You do that by going to Windows Programs and selecting Add/Change for the AutoCad Electrical Software.


After adding the IEC Menus, you should have a sample of IEC drawings in your Projects folder.


Now the real fun begins.


I have been spending the past 8 months, on and off, redesigning our schematics into IEC format.


I recommend getting the following books to get you started.


IEC 81346-1

IEC 81346-2

IEC 61666

IEC 60204

IEC 61082

IEC 60445


Be prepared to spend about a $1000.


Then spend a lot of time reading and rereading these books.


Now you are close to starting to convert the schematics from JIC to IEC format.


You will have to create all your own symbols for your unique parts.


IEC is a completely different way of looking at machine documentation. I do like it now but it was painful getting to where I am.


Good Luck.

You can actually find a lot of the information with Google as far as the different IEC code specs. For instance IEC 61346

is one bit of information you will need. The place I worked for was to cheap to shell out a thousand bucks so I had to learn by example. Read this document from  Moeller I previously posted its very helpful.


One very important thing to learn with IEC drawings is they use Location (+) and function (=) codes. Usually in the right hand side of the titleblock you will see some thing like this.



In this sample

RRM - is the function code for Reversing Rolling Mill

QP1  - is the location code for the Panel (multi door panel so there might also be +QP1.1, +QP1.2)


I have attached a couple documents I found on the web that might help explain some of the IEC symbols

There is a very good Autodesk training guide for IEC fundamentals using AutoCAD Electrical.  Check it out via Ascent... As for custom symbols, web searches or links from the previous posts are really very helpful..


Good luck!

An interesting thread.  I do not need to know but thanks to those who responded.  If I ever need to I know where to go.
