The RAFIX 30 FS+ FLEXLAB (Flexible labelling) pushbutton gives the user the opportunity to individually label control components. In order to label the components, RAFI offers a DIN A4 labelling sheet complete with pre-punched labels that can be printed using commercially available office printers (preferably laser printers). After printing, the legend inserts can be removed from the sheet and then inserted and assembled into the color bezel with the help of the fine retaining lugs.
