Core colors according to EN 61918
Adaptation of core colors for cables ZB9030, ZB9032 and ZK1090-3xxxx-xxxx
For standardization, the core colors of the ZB9030, ZB9032 and ZK1090-3xxx-xxxx cables have
been changed to the EN61918 core colors: yellow, orange, white, blue. So there are different color
codes in circulation. The electrical properties of the cables have been retained when the core colors
were changed.
