The information in this section covers installation considerations for the Rosemount 2051 with FOUNDATION fieldbus. A Quick Installation Guide for FOUNDATION fieldbus (document number 00825-0200-4101) is shipped with every transmitter to describe basic pipe-fitting and wiring procedures for initial installation. Dimensional drawings for each 2051 variation and mounting configuration are also included.

Procedures and instructions in this section may require special precautions to ensure the safety of the personnel performing the operation. Information that raises potential safety issues is indicated with a warning symbol ( ). Refer to the following safety messages before performing an operation preceded by this symbol.

Explosions could result in death or serious injury:

Installation of this transmitter in an explosive environment must be in accordance with the appropriate local, national, and international standards, codes, and practices. Please review the approvals section of the 2051 reference manual for any restrictions associated with a safe installation.

•Before connecting a Field Communicator in an explosive atmosphere, ensure the instruments in the loop are installed in accordance with intrinsically safe or non-incendive field wiring practices.

•In an Explosion-Proof/Flameproof installation, do not remove the transmitter covers when

power is applied to the unit.

Process leaks may cause harm or result in death.

•Install and tighten process connectors before applying pressure. 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.
