1.4 OPTIFLUX 2000 / 4000

1.4.1 Compact versions

OPTIFLUX 2300 C / 4300 C is certified as a group II, category 2 GD equipment, if fitted with an IFC
300 signal converter without Ex ia signal in/outputs or as a group II, category 2 (1) GD equipment,
if fitted with a signal converter with Ex ia signal in/outputs.
It is therefore suitable for installation in gas hazardous areas zone 1 or 2, gas group IIC,
temperature class T6 (or T5)...T3 and dust hazardous areas zone 21 or zone 22, surface

temperature T85...150°C. Additionally, the Ex ia signal inputs/outputs of the signal converter

may run or originate from a Zone 0 Gas hazardous area.
