NOTICE Read this manual before working with the product. For personal and system safety and for optimum product performance, make sure you thoroughly understand the contents before installing, using, or maintaining this product. For technical assistance, contacts are listed below: Customer Central (Technical support, quoting, and order-related questions.) • United States: 1-800-999-9307 (7:00 am to 7:00 pm Central Time) • Asia Pacific: 65 777 8211 • Europe/Middle East/Africa: 49 (8153) 9390 North American Response Center (Equipment service needs.): 1-800-654-7768 (24 hours - includes Canada) Outside of these areas, contact your local Emerson™ representative. WARNING Explosions Explosions could result in death or serious injury. In an explosion-proof/flameproof installation, do not remove the transmitter covers when power is applied to the unit. Installation of device in an explosive environment must be in accordance with appropriate local, national, and international standards, codes, and practices. Review the Product Certifications section of the Rosemount 3051 Product Data Sheet for any restrictions associated with a safe installation. Before connecting a handheld communicator in an explosive atmosphere, ensure the instruments are installed in accordance with intrinsically safe or non-incendive field wiring practices. WARNING Process leaks Process leaks may cause harm or result in death. Install and tighten process connectors before applying pressure. Do not attempt to loosen or remove flange bolts while the transmitter is in service. WARNING Electrical shock Electrical shock can result in death or serious injury. Avoid contact with the leads and terminals. High voltage that may be present on leads can cause electrical shock. WARNING Replacement equipment Replacement equipment or spare parts not approved by Emerson for use as spare parts could reduce the pressure retaining capabilities of the transmitter and may render the instrument dangerous. Use only bolts supplied or sold by Emerson as spare parts. 2

For safe assembly of manifold to traditional flange, bolts must break back plane of flange web (i.e., bolt hole) but must not contact sensor module housing. Severe changes in the electrical loop may inhibit HART® Communication or the ability to reach alarm values. Therefore, Rosemount™ absolutely cannot warrant or guarantee that the correct Failure alarm level (High or Low) can be read by the host system at the time of annunciation. WARNING Physical access Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end users’ equipment. This could be intentional or unintentional and needs to be protected against. Physical security is an important part of any security program and fundamental to protecting your system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for all systems used within the facility. CAUTION Nuclear applications The products described in this document are not designed for nuclear-qualified applications. Using non-nuclear qualified products in applications that require nuclear-qualified hardware or products may cause inaccurate readings. For information on Rosemount nuclear-qualified products, contact your local Emerson Sales Representative. 3
