NOTICE
This installation guide provides basic guidelines for Rosemount
2051 transmitters. It does not provide instructions for configuration, diagnostics,
maintenance, service, troubleshooting, Explosion-proof, Flameproof, or intrinsically safe
(I.S.) installations. Refer to the 2051 reference manual (document number
00809-0100-4107) for more instruction. This manual is also available electronically on
www.emersonprocess.com/rosemount.
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 2051 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 may cause harm or result in death.
To avoid process leaks, only use the o-ring designed to seal with the corresponding flange
adapter.
Electrical shock can result in death or serious injury.
Avoid contact with the leads and the 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. Only use plugs, adapters, glands or conduit with a compatible thread form
when closing these entries.

System Readiness
Confirm HART Revision Capability
If using HART based control or asset management systems, please confirm the
HART capability of those systems prior to transmitter installation. Not all
systems are capable of communicating with HART Revision 7 protocol. This
transmitter can be configured for either HART Revision 5 or 7.
For instructions on how to change the HART revision of your transmitter, see
page 15.
Confirm Correct Device Driver
Verify the latest Device Driver (DD/DTM) is loaded on your systems to ensure
proper communications.
Download the latest Device Driver files at www.emersonprocess.com or
www.hartcomm.org.

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 6 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. If bolt material is
not shown in Table 2, 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
Figure 2 for initial torque value.
4. Torque the bolts to the final torque value using the same crossing pattern. See
Figure 2 for final torque value.
5. Verify that the flange bolts are protruding through the isolator plate before
applying pressure.

Inline gage transmitter orientation
The low side pressure port (atmospheric reference) on the inline gage transmitter
is located in the neck of the transmitter, behind the housing. The vent path is 360°
around the transmitter between the housing and sensor. (See Figure 7.)
Bolt Material Head Markings Initial Torque Final Torque
Carbon Steel (CS) 300 in.-lbs. 650 in.-lbs.
Stainless Steel (SST) 150 in.-lbs. 300 in.-lbs.
Failure to install proper flange adapter O-rings may cause process leaks, which can result in death or serious
injury. The two flange adapters are distinguished by unique O-ring grooves. Only use the O-ring that is designed
for its specific flange adapter, as shown below.
Keep the vent path free of any obstruction, including but not limited to paint, dust, and
lubrication by mounting the transmitter so that the contaminants can drain away.

Step 2: Consider housing rotation
To improve field access to wiring or to better view the optional LCD display:
Step 3: Set the switches
Set Alarm and Security switch configuration before installation as shown in
Figure 8.
The Alarm switch sets the analog output alarm to high or low.
- Default alarm is high.
The Security switch allows ( ) or prevents ( ) any configuration of the
transmitter.
- Default security is off ( ).
Use the following procedure to change the switch configuration:
1. If the transmitter is installed, secure the loop, and remove power.
2. Remove the housing cover opposite the field terminal side. Do not remove the
instrument cover in explosive atmospheres when the circuit is live.
3. Slide the security and alarm switches into the preferred position using a small
screwdriver.
4. Reattach the transmitter cover. The cover must be fully engaged to comply
with explosion-proof requirements.
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. Re-tighten the housing rotation set screw.

Step 4: Connect the wiring and power up
Shielded twisted pair cable should be used for best results. Use 24 AWG or larger
wire that does not exceed 5,000 feet (1500 meters) in length. 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.

Figure 10. Wiring the Transmitter (1-5 Vdc Low Power)
Use the following steps to wire the transmitter:
1. Remove the housing cover on the FIELD TERMINALS side.
2. Connect the Leads and shown in Figure 9 on page 9 or Figure 10.
3. Ground housing to fulfill local grounding regulations.
4. Ensure proper grounding. It is important that the instrument cable shield:
a. Be trimmed close and insulated from touching the transmitter housing.
b. Be connected to the next shield if cable is routed through a junction box.
c. Be connected to a good earth ground at the power supply end.
5. If transient protection is needed, refer to section “Grounding for Transient
Terminal Block” for grounding instructions.
6. Plug and seal unused conduit connections.
7. Replace the housing cover.
Installation of the transient protection terminal block does not provide transient protection
unless the 2051 case is properly grounded.
Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical
equipment.
Do not connect the powered signal wiring to the test terminals. Power could damage the test
diode in the terminal block.
