In gas atmospheres, when selecting group IIB or IIC for the intrin-
sically safe circuits, all intrinsically safe circuits and the LB 480
detector must be operated completely in the selected group IIB or
IIC.
Installation of the probe with protection level "ia" allows the safe
use of measuring instruments that otherwise may be used only in
zone 0 or zone 20.
