Installation of intrinsically safe circuits

Installation (a summary):
Upon installation, the standards and regulations in force must be observed (Cenelec, Atex 118a,). Intrinsically safe circuits should be separated from non IS circuits. At bare live connections (terminals) a minimum distance of 50 mm should be allowed between IS and non IS circuits. Between IS circuits the distance should be at minimum 6 mm. Intrinsically safe cables and wires should be in light blue.
