Overpressure monitoring
You must connect an appropriate purging unit in the case of analyzers with type of protection
"Pressurized enclosure Ex px or Ex pz". This purging unit ensures that the overpressure is
monitored reliably and that the volume flow is monitored fail-safe (redundant).
If an analyzer is used with type of protection "Pressurized enclosure Ex pz" in Zone 2, you must
provide a purging unit with type of protection "Ex px" when connecting combustible or
occasionally explosive sample gases.
