Figure Isolation examples for conductive parts
In accordance with DIN 60079-14 (VDE 0165-1), intrinsically safe circuits, the ends stranded and fine-stranded conductors must be
protected against splaying (e.2.1 for output terminal blocks between isolated intrinsically safe circuits (d2 mm) and between intrinsi-
cally safe circuits and non-intrinsically safe circuits (d3 mm)
