Safety messages
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 by 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 Rosemount 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.
