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 this guide 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.
Use appropriately rated Ex adaptors, blanking elements, or glands during installation.
Keep process insulation at least 1-in. (25 mm) from transmitter connection.
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.
Conduit/cable entries
Unless marked, the conduit/cable entries in the transmitter housing use a 1/2–14 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, adapters, or
glands in cable/conduit entries.

1.5 Bolting considerations
If the transmitter installation requires assembly of the process flanges, manifolds,
or flange adaptors, 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 1 illustrates
common transmitter assemblies with the bolt length required for proper
transmitter assembly.

A. Transmitter with coplanar flange
B. Transmitter with coplanar flange and optional flange adaptors
C. Transmitter with traditional flange and optional flange adaptors
D. Transmitter with coplanar flange and optional Rosemount Conventional Manifold and
flange adapters
Bolts are typically carbon steel or stainless steel. Confirm the material by viewing
the markings on the head of the bolt and referencing Table 1. If bolt material is
not shown in Table 1, contact the local Emerson Process Management
representative for more information.
Use the following bolt installation 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 1 for initial torque value.
4. Torque the bolts to the final torque value using the same crossing pattern.
See Table 1 for final torque value.
5. Verify the flange bolts are protruding through the sensor module before
applying pressure.

Failure to install proper flange adaptor O-rings may cause process leaks, which can result in death or
serious injury. The two flange adaptors are distinguished by unique O-ring grooves. Only use the
O-ring designed for its specific flange adaptor, as shown below:
A. Flange adaptor
B. O-ring
C. PTFE based (profile is square)
D. Elastomer (profile is round)
Whenever the flanges or adaptors are removed, visually inspect the O-rings. Replace them if there are
any signs of damage, such as nicks or cuts. If you replace the O-rings, re-torque the flange bolts and
alignment screws after installation to compensate for seating of the O-rings.

1.7 In-line gage transmitter orientation
The low side pressure port (atmospheric reference) on the in-line gage
transmitter is located under the sensor module neck label. (See Figure 3.)
Keep the vent path free of any obstruction, including but not limited to paint,
dust, and lubrication by mounting the transmitter so any contaminants can drain
away.

A. Low side pressure port (under neck label)
2.0 Consider housing rotation
To improve field access to wiring or to better view the optional LCD display:
1. Loosen the housing rotation set 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. Retighten the housing rotation set screw up to 30 in-lb.

3.0 Set switches and jumpers
If alarm and security adjustment option is not installed, the transmitter will
operate normally with the default alarm condition alarm “high” and the security
“off”.
1. Do not remove the transmitter covers in explosive atmospheres when the
circuit is live. If the transmitters is live, set the loop to manual and remove
power.
2. Remove the electronics compartment cover. On the PlantWeb housing the
cover is opposite the field terminals side, or on the junction box housing
remove the terminal block cover. Do not remove the housing cover in
explosive environments.
3. On the PlantWeb housing, slide the security and alarm switches into the
preferred position by using a small screwdriver (An LCD display or an
adjustment module must be in place to activate the switches). On the junction
box housing pull the pins out and rotate 90° into desired position to set the
security and alarm.
4. Reinstall the housing cover so metal contacts metal to meet explosion-proof
requirements.

4.0 Connect wiring and power up
Use the following steps to wire the transmitter:
1. Remove and discard orange conduit plugs.
2. Remove the housing cover labeled “Field Terminals.”
3. Connect the positive lead to the “+” terminal, and the negative lead to the “–”
terminal.
Note
Do not connect the power across the test terminals. Power could damage the test diode in
the test connection. Twisted pairs yield best results. Use 24 AWG to 14 AWG wire and do
not exceed 5,000 ft (1500 m). For single compartment housing (Junction Box housing),
shielded signal wiring should be used in high EMI/RFI environments.
4. Plug and seal the unused conduit connection with the provided conduit plug.
5. If applicable, install wiring with a drip loop. Arrange the drip loop
so the bottom is lower than the conduit connections and the
transmitter housing.
6. Reinstall the housing cover and tighten so the cover is fully seated with metal
to metal contact between the housing and cover in order to meet explosion
proof requirements.
The figures below show the wiring connections necessary to power a Rosemount
3051S and enable communications with a hand-held Field Communicator.

A. RL ≥ 250 Ω
B. Power supply
Note
Installation of the transient protection terminal block does not provide transient protection
unless the Rosemount 3051S case is properly grounded.
NOTICE
When the enclosed threaded plug is utilized in the conduit opening, it must be installed with a
minimum thread engagement in order to comply with explosion-proof requirements. For
straight threads, a minimum of seven threads must be engaged. For tapered threads, a
minimum of five threads must be engaged.
