IMPORTANT NOTICEThis 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 00809-0100-4101) for more instruction. This manual is also available electronically on www.emersonprocess.com/rosemount.
WARNINGExplosions 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.

STEP 1 CONTINUED...C. Bolting ConsiderationsIf 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.

D. 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.
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.

E. Inline Gage Transmitter OrientationThe 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 contaminants can drain away.Figure 3. Inline Gage Transmitter
STEP 2: CONSIDER HOUSING ROTATIONTo improve field access to wiring or to better view the optional LCD display:
STEP 3: SET THE JUMPERSIf alarm and security jumpers are not installed, the transmitter will operate normally with the default alarm condition alarm high and the security off.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. Reposition the jumper. Avoid contact with the leads and the terminals. See Figure 4 for
the location of the jumper and the ON and OFF positions. 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. Retighten the housing rotation set screw.
