Installation
Note
Do not connect the power across the test terminals. Power could damage the test diode in the test
connection.
3. If the optional process temperature input is not installed, plug and seal the unused conduit
connection. If the optional process temperature input is being utilized, see
temperature input (Pt 100 RTD sensor)” on page 76
for more information.
When the enclosed pipe plug is utilized in the conduit opening, it must be installed with a minimum
engagement of five threads in order to comply with flameproof/explosion-proof requirements.
4. 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.
5. Reinstall the housing cover and tighten so that metal contacts metal to meet
flameproof/explosion-proof requirements.

Note
Installation of the transient protection terminal block does not provide transient protection unless the
Rosemount 3051SMV housing is properly grounded. See
for more information.
Install optional process temperature input (Pt 100 RTD sensor)
Note
To meet ATEX/IECEx Flameproof certification, only ATEX/IECEx Flameproof cables (temperature input
code C30, C32, C33, C34 or customer supplied equivalent) may be used.
1. Mount the Pt 100 RTD Sensor in the appropriate location.
Note
Use shielded four-wire cable for the process temperature connection.
