IMPORTANT NOTICE
This installation guide provides basic guidelines for the Rosemount®
Rosemount 3244MV. It does not provide instructions for detailed
configuration, diagnostics, maintenance, service, troubleshooting,
explosion-proof, flameproof, or intrinsically safe (I.S.) installations.
Refer to the Rosemount 3244MV reference manual (document
number 00809-0100-4769) for more instruction. The manual and this
QIG are also available electronically on www.rosemount.com.
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 this manual for any restrictions associated with a safe
installation.
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
• Install and tighten thermowells or sensors before applying
pressure.
• Do not remove the thermowell while in operation.
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.

STEP 1: MOUNT THE TRANSMITTER
Mount the transmitter at a high point in the conduit run to prevent
moisture from draining into the transmitter housing.
Typical Direct Mount Installation
1. Mount the thermowell to the process container wall. Install and
tighten thermowells. Perform a leak check.
2. Attach any necessary unions, couplings, and extension fittings.
Seal the fitting threads with silicone or tape (if required).
3. Screw the sensor into the thermowell or directly into the process
(depending on installation requirements).
4. Verify all sealing requirements.
5. Attach the transmitter to the thermowell/sensor assembly. Seal all
threads with silicone or tape (if required).
6. Install field wiring conduit into the open transmitter conduit entry
(for remote mounting) and feed wires into the transmitter housing.
7. Pull the field wiring leads into the terminal side of the housing.
8. Attach the sensor leads to the transmitter sensor terminals (the
wiring diagram is located inside the housing cover).
9. Attach and tighten both transmitter covers.

Typical Remote Mount Installation
1. Mount the thermowell to the process container wall. Install and
tighten thermowells. Perform a leak check.
2. Attach a connection head to the thermowell.
3. Insert sensor into the thermowell and wire the sensor to the
connection head (the wiring diagram is located inside the
connection head).
4. Mount the transmitter to a 2-in. (50 mm) pipe or a panel using one
of the optional mounting bracket (B4 bracket is shown below).
5. Attach cable glands to the shielded cable running from the
connection head to the transmitter conduit entry.
6. Run the shielded cable from the opposite conduit entry on the
transmitter back to the control room.
7. Insert shielded cable leads through the cable entries into the
connection head / transmitter. Connect and tighten cable glands.
8. Connect the shielded cable leads to the connection head terminals
(located inside the connection head) and to the sensor wiring
terminals (located inside the transmitter housing).

STEP 2: WIRE AND APPLY POWER
1. Remove terminal block cover
2. Ensure the sensor wires are
inside the terminal area.
3. Connect sensor wires according
to Figure 1.
4. Tighten sensor terminal screws.

STEP 2 CONTINUED...
Power the Transmitter
The transmitter requires between 9 and 32 Vdc to operate and provide
complete functionality. The dc power supply should provide power with
less than 2% ripple.
Power Filter
A fieldbus segment requires a power conditioner to isolate the power
supply filter and decouple the segment from other segments attached
to the same power supply.
Power Connections
Use copper wire of sufficient size to ensure that the voltage across the
transmitter power terminals is not below 9 Vdc.
To connect power to the transmitter, follow the steps below:
1. Remove the transmitter cover to expose the transmitter terminal
block. Do not remove transmitter covers in explosive atmospheres
when the circuit it live.
2. Connect the power leads to the terminals marked “+” and “T”. The
power terminals are not polar sensitive, meaning that the electrical
polarity of the power leads is not significant when connected to the
power terminals. The use of crimped lugs is recommended when
wiring to screw terminals.
3. Tighten the terminal screws to ensure adequate contact. No
additional power wiring is necessary.
4. Replace the transmitter cover, tightening the cover threads at least
one-third turn after the o-ring contacts the housing. Both
transmitter covers must be fully engaged to meet explosion-proof
requirements.
NOTE
After installation, it may take several seconds for the LCD meter to
function once power is applied to the transmitter.
