2.6.3 Separation between Intrinsically Safe and Non-Intrinsically Safe I/O
Modules
The separation wall is attached to the backplane between I/O modules with intrinsically safe
circuits and I/O modules with non-intrinsically safe circuits to ensure a clearance of 50 mm
between intrinsically safe circuits and other circuits. The separation wall can be installed on
both backplanes with and without a label carrier.
