Note
Each transmitter is marked with a tag indicating the approvals. Install the transmitter according to all
applicable installation codes, and approval and installation drawings (see Product Data Sheet
). Verify the
operating atmosphere of the transmitter is consistent with the hazardous location certifications. Once a
device labeled with multiple approval types is installed, it should not be reinstalled using any of the other
labeled approval types. To ensure this, the approval label should be permanently marked to distinguish
the approval type(s) used.
