Note
Grounding the transmitter case via threaded conduit connection may not provide sufficient
ground continuity.
2.10 Hazardous locations certifications
Individual transmitters are clearly marked with a tag indicating the approvals they carry.
Transmitters must be installed in accordance with all applicable codes and standards to
maintain these certified ratings. Refer to “Hazardous locations certifications” on page 177 for
information on these approvals.

market today. The 306 Integral Manifold is used with the 3051T in-line transmitters to provide
