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 3051 reference manual for any restrictions associated with a
safe installation.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following
conditions.
This device may not cause harmful interference. This device must accept any interference
received, including interference that may cause undesired operation.
This device must be installed to ensure a minimum antenna separation distance of 8 in. (20
cm) from all persons.
The Power Module may be replaced in a hazardous area. The Power Module has surface
resistivity greater than one gigaohm and must be properly installed in the wireless device
enclosure. Care must be taken during transportation to and from the point of installation to
prevent a potential electrostatic charging hazard.
Polymer enclosure has surface resistivity greater than one gigaohm. Care must be taken
during transportation to and from the point of installation to prevent a potential
electrostatic charging hazard.
Process leaks may cause harm or result in death.

Electrical shock can result in death or serious injury.

The Rosemount 3051 and all other wireless devices should be installed only after the Smart
Wireless Gateway has been installed and is functioning properly. Wireless devices should
also be powered up in order of proximity from the Smart Wireless Gateway, beginning with
the closest. This will result in a simpler and faster network installation.
ii
Before connecting a HART-based communicator in an explosive atmosphere, make
sure the instruments in the loop are installed in accordance with intrinsically safe or
non-incendive field wiring practices.
To avoid process leaks, only use the o-ring designed to seal with the corresponding
flange adapter.
Avoid contact with the leads and the terminals. High voltage that may be present on
leads can cause electrical shock.
