Safety Messages
NOTICE
This guide provides basic guidelines for Rosemount 3051 Wireless Transmitters. It does not provide
instructions for configuration, diagnostics, maintenance, service, troubleshooting or Intrinsically Safe
(I.S.) installations. Refer to the Rosemount 3051 Wireless Reference Manual for more instruction. This
manual is also available electronically on Emerson.com/Rosemount.
Shipping considerations for wireless products:
The unit was shipped to you without the power module installed. Remove the power module prior to
shipping the unit.
Each power module contains one “D” size primary lithium-thionyl chloride battery. Primary lithium
batteries are regulated in transportation by the U.S. Department of Transportation, and are also
covered by IATA (International Air Transport Association), ICAO (International Civil Aviation
Organization), and ARD (European Ground Transportation of Dangerous Goods). It is the responsibility
of the shipper to ensure compliance with these or any other local requirements. Consult current
regulations and requirements before shipping.
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 handheld 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.
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.

1 Wireless considerations
1.1 Power up sequence
The power module should not be installed on any wireless device until the
Emerson™ Wireless Gateway (Gateway) is installed and functioning properly.
This transmitter uses the green power module (order model number
701PGNKF). Wireless devices should also be powered up in order of proximity
from the Gateway, beginning with the closest. This will result in a simpler and
faster network installation. Enable Active Advertising on the Gateway to
ensure that new devices join the network faster. For more information, see
the Emerson Wireless Gateway Reference Manual.
1.2 Connecting the transmitter with a Field Communicator
In order for the Field Communicator to interface with the Rosemount 3051
Wireless transmitter, the power module must be connected. This transmitter
uses the green power module (order model number 701PGNKF). Figure 1-1
shows how to connect the Field Communicator to the transmitter. Open the
power module compartment to hook up the leads.

2.1.4 Bolting considerations
If the transmitter installation requires assembly of the process flanges,
manifolds, or flange adapters, follow these 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 (CS) or stainless steel (SST). 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.
Procedure
1. Carbon steel bolts do not require lubrication and the stainless steel
bolts are coated with a lubricant to ease installation. However, no
additional lubricant should be applied when installing either type of
bolt.
2. Finger-tighten the bolts.
3. Torque the bolts to the initial torque value using a crossing pattern.
See Table 2-1 for initial torque value.
4. Torque the bolts to the final torque value using the same crossing
pattern. See Table 2-1 for final torque value.
5. Verify the flange bolts are protruding through the isolator plate before
applying pressure.

2.1.5 In-line gage transmitter orientation
The low side pressure port (atmospheric reference) on the in-line gage
transmitter is located in the neck of the transmitter, behind the housing. The
vent path is between the housing and sensor of the transmitter (see Figure
2-11).
Keep the vent path free of any obstruction, including but not limited to paint,
dust, and lubrication by mounting the transmitter so that the process can
drain away.

2.1.6 Installing high pressure coned and threaded connection
The transmitter comes with an autoclave connection designed for high
pressure applications. Follow the steps below to properly connect the
transmitter to your process:
Procedure
1. Apply a process-compatible lubricant to the gland nut threads.
2. Slip the gland nut onto the tube, then thread the collar onto the tube
end (the collar is reverse threaded).
3. Apply a small amount of process-compatible lubricant applied to the
tube cone to help prevent galling and facilitate sealing. Insert the
tubing into the connection and tighten finger tight.
4. Tighten the gland nut to a torque of 25 ft-lb.
Note
A weep hole has been designed into the transmitter for safety and leak
detection. If fluid begins to leak from the weep hole, isolate the
process pressure, disconnect the transmitter, and reseal until the leak
is resolved.
2.2 Consider housing rotation
To improve visibility of optional LCD display:
Procedure
1. Loosen the housing rotation screw.
2. First rotate the housing clockwise to the desired location. If the desired
location cannot be achieved due to thread limit, rotate the housing
counter clockwise to the desired location (up to 360° from thread
limit).
3. Re-tighten the housing rotation screw (see Figure 2-12).
