Barcode Stickers

Where is the best spot to place the barcode stickers? I have been told the drawings are a good place but I am often updating the cad drawings.

Any suggestions or are they not worth worrying about?

 

I Stick them on the Front of the switches under the front cover for easy location later without having to remove the Switch to read the sticker on the back. On the Relay Dimmer units I put them again on the front below the Cbus Connections so Again you can read them without pulling the relay out !.

I have suggested this in the past But I must be the only one that has to go back to Old jobs done by others to make changes !.
