IMPORTANT NOTICE
This installation guide provides basic guidelines for Rosemount 2051 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 2051 PROFIBUS PA reference
manual (document number 00809-0300-4101) for more instruction. This manual is also available
electronically on www.emersonprocess.com/rosemount.
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. Please review the approvals section
of the 2051 PROFIBUS PA reference manual for any restrictions associated with a safe installation.
• 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.

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 1 illustrates common transmitter assemblies with the bolt
length required for proper transmitter assembly.
Figure 1. Common Transmitter Assemblies
Bolts are typically carbon steel or stainless steel. Confirm the material by viewing the
markings on the head of the bolt and referencing Figure 2. If bolt material is not shown in
Figure 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.

O-rings with Flange Adapters
WARNING
Whenever the flanges or adapters 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
PTFE o-ring.

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.

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 3.)
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.
Figure 3. Inline Gage Low Side Pressure Port
STEP 2: 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.

STEP 3: SET JUMPERS AND SWITCHES
Security
After the transmitter is configured, you may want to protect the configuration data from
unwarranted changes. Each transmitter is equipped with a security jumper that can be
positioned “ON” to prevent the accidental or deliberate change of configuration data. The
jumper is labeled “Security.”
Simulate
The simulate jumper is used in conjunction with the Analog Input (AI) block. This jumper is
used to simulate the pressure measurement and is used as a lock-out feature for the AI
block. To enable the simulate feature, the jumper must be moved to the “ON” position after
power is applied. This feature prevents the transmitter from being accidently left in simulate
mode.

STEP 4: CONNECT WIRING AND POWER UP
Use the following steps to wire the transmitter:
1. Remove the housing cover on the FIELD TERMINALS side.
2. Connect the power leads to the terminals indicated on the terminal block label.
• Power terminals are polarity insensitive - connect positive or negative to either terminal
3. Ensure proper grounding. It is important that the instrument cable shield:
• be trimmed close and insulated from touching the transmitter housing
• be connected to the next shield if cable is routed through a junction box
• be connected to a good earth ground at the power supply end
4. Plug and seal unused conduit connections.
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. Replace the housing cover.

Signal Wiring Grounding
Do not run signal wiring in conduit or open trays with power wiring, or near heavy electrical
equipment. Grounding terminations are provided on the outside of the electronics housing
and inside the Terminal Compartment. These grounds are used when transient protect
terminal blocks are installed or to fulfill local regulations. See Step 2 below for more
information on how the cable shield should be grounded.
1. Remove the Field Terminals housing cover.
2. Connect the wiring pair and ground as indicated in Figure 7. The cable shield should:
a. Be trimmed close and insulated from touching the transmitter housing.
b. Continuously connect to the termination point.
c. Be connected to a good earth ground at the power supply end.
Figure 7. Wiring
3. Replace the housing cover. It is recommended that the cover be tightened until there is
no gap between the cover and the housing.
4. Plug and seal unused conduit connections.
Power Supply
The dc power supply should provide power with less than two percent ripple. The
transmitter requires between 9 and 32 Vdc at the terminals to operate and provide
complete functionality.
Power Conditioner
The DP/PA Coupler / Link often includes an integrated power conditioner.
Grounding
Transmitters are electrically isolated to 500 Vac rms. Signal wiring can not be grounded.
Shield Wire Ground
Shield wire usually requires a single grounding point to avoid creating a ground loop. The
ground point is typically at the power supply.
