12、n systems If necessary, additional symbols may be used for other important elements of the object to be protected. These symbols should be simple and they have to be explained in a legend in the LPS design drawings. In case of an isolated protection system (see IEC 62305-1 and IEC 62305-3) this has
13、to be stated in the LPS design drawings including required separation distances. In case of preparing a coloured kind of drawing, the colours should be used as follows: building black, lightning protection red, metal sheets green, metal structure blue.
