1 About this guide
This guide provides basic guidelines for Rosemount 3051 Transmitters. It
does not provide instructions for configuration, diagnostics, maintenance,
service, troubleshooting, Explosion-Proof, Flame-Proof, or intrinsically safe
(I.S.) installations. Refer to the Rosemount 3051 Reference Manual for more
instructions. This manual is also available electronically on Emerson.com/

WARNING
Explosions
Explosions could result in death or serious injury.
Installation of this transmitter in an explosive environment must be in
accordance with the local, national, and international standards, codes,
and practices. Review product certifications for any restrictions
associated with a safe installation.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 that 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.

WARNING
Process leaks
Process leaks could result in death or serious injury.Process leaks may cause
harm or result in death.Process leaks may cause harm or result in death.
Install and tighten process connectors before applying pressure.
To avoid process leaks, only use the O-ring designed to seal with the
corresponding flange adapter.
Electrical shock
Electrical shock could cause death or serious injury.Electrical shock can result
in death or serious injury.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.
Conduit/cable entries
Unless marked, the conduit/cable entries in the transmitter housing use a
½–14 NPT thread form. Entries marked “M20” are M20 × 1.5 thread form.
On devices with multiple conduit entries, all entries will have the same
thread form. Only use plugs, adapters, glands, or conduit with a compatible
thread form when closing these entries.
When installing in a hazardous location, use only appropriately listed or Ex
certified plugs, glands, or adapters in cable/conduit 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.

2.1.4 Bolting consideration
If the transmitter installation requires assembly of the process flanges,
manifolds, or flange adapters, follow the assembly guidelines to ensure a
tight seal for optimal performance characteristics of the transmitters.
Use only bolts supplied with the transmitter or sold by Emerson as spare
parts. Figure 2-10 illustrates common transmitter assemblies with the bolt
length required for proper transmitter assembly.

Bolts are typically carbon steel or stainless steel. Confirm the material by
viewing the markings on the head of the bolt and referencing Table 2-1. If
bolt material is not shown in Table 2-1, contact a local Emerson
representative for more information.
Carbon steel bolts do not require lubrication, and the stainless steel bolts are
coated with a lubricant to ease installation. However, do not apply additional
lubricant when installing either type of bolt.
