NOTE
Each transmitter is clearly marked with a tag indicating the approvals. Install
the transmitter in accordance with all applicable installation codes and
approval and installation drawings (See Appendix B: Hazardous Area
Approvals). Verify that the operating atmosphere of the transmitter is
consistent with the appropriate hazardous locations certifications.
IMPORTANT
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 used from
the unused approval type(s).
If you are mounting the transmitter directly to the sensor assembly, use the
process shown in Figure 2-6. If you are mounting the transmitter apart from
the sensor assembly, use conduit between the sensor and transmitter. The
transmitter accepts male conduit fittings with
