In case of explosion proof type for CENELEC ATEX, FM, and CSA certification, connect wiring as shown in the figure below.

In case of the explosion proof type, the protective

grounding of remote flowtube must be connected to a suitable IS grounding system. In that case,

(functional grounding terminal) need not be connected.
