WARNING
IMPORTANT NOTICE
00825-0100-4593, Rev BA
Rosemount 1151
Explosions could result in death or serious injury:
Installation of this transmitter in an explosive environment must be in accordan ce with t he ap propriat e
local, national, and international standards, code s, and practices. Pl ease review the approval s section
of the 1151 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/Flame-Proof 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.
This installation guide provides basic guidelines for Rosemount 1151 transmitters. It does not provide
instructions for configuration, diagnostics, maintenance, service, troubleshooting, Explosion-Proof,
Flame-Proof, or intrinsically safe (I.S.) installat i ons. Refer to the Rosemount 1151 reference manual
(document number 00809-0100-4360) for more instruction. This manual is also available electr onically

C. O-rings with Flange Adapters
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.
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.

STEP 2: CONSIDER HOUSING ROTATION
Housing Lock Nut

Rosemount 1151
To improve field access or to better view the optional LCD display:
1. Loosen the housing lock nut.
2. Rotate the housing clockwise to the desired position – up to 90° from its original position.
Over rotating will damage the transmitter.
3. If the desired position is attained, tighten the housing lock nut.
4. If the desired position cannot be reached because the housing will not rotate further,
rotate the housing counterclockwise until in the desired position (up to 90° from its
original position).
5. Tighten the housing lock nut to 420-in/lb. Use a sealing compound
(Loctite 222 – Small Screw Threadlocker) on the threads to ensure a watertight seal on
the housing.
NOTE
If the desired position cannot be attained within the 90° limit, the transmitter will need to be
disassembled. See the Rosemount 1151 reference manual (document number
00809-0100-4360) for further instruction.

Use the following steps to wire the transmitter:
1. Remove the housing cover on the side marked TERMINALS on the nameplate.
2. Connect the po sitive lead to the “+” terminal and the negative lead to the “–” terminal.
Figure 1. Field Wiring Diagram
Installation of the transient protection ter minal block does n ot provide transien t protection unl ess the 1151
case is properly grounded.
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
NOTE
Do not connect the powered signal wiring to the test terminals. Power could damage the test
diode in the test connection. Twisted pair cable should be used for best results. In high
EMI/RFI environments, use either transient terminal block or shielded signal wiring. Use 12
to 24 AWG wire and do not exceed 5,000 feet (1500 meters).

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 housin g cover.
