Note
Before installing the transmitter, confirm the correct device driver is loaded on the host systems. See
System readiness.
NOTICE
This installation guide provides basic guidelines for Rosemount 3051 transmitters. It does not provide
instructions for configuration, diagnostics, maintenance, service, troubleshooting, Explosion-Proof,
Flameproof, or intrinsically safe (I.S.) installations. Refer to the Rosemount 3051 Reference Manual
(document number 00809-0100-5007) for more instruction. This manual is also available
electronically on www.emerson.com.
WARNING
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. Review the approvals section of the
Rosemount 3051 Reference Manual for any restrictions associated with a safe installation.
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.
In an explosion-proof/flameproof installation, do not remove the transmitter covers when power is
applied to the unit.
Process leaks could result in death or serious injury.
To avoid process leaks, only use the o-ring designed to seal with the corresponding flange adapter.
Electrical shock could cause death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause
electrical shock.
Conduit/cable entries
Unless otherwise marked, the conduit/cable entries in the housing enclosure use a ½–14 NPT form.
Only use plugs, adapters, glands, or conduit with a compatible thread form when closing these entries.
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.
