2-16
FIELD INSTALLATION
PROCEDURE
1. Review Installation
Considerations
1. Review the installation considerations described on pages 2-6
through 2-15 in this chapter to determine the location for the
Model 3095FT. If the installation includes the Remote Power
Supply, also review the sunlight considerations described on page
3-8.
2. Mount Transmitter and
Install Bolts
2. Mount the Model 3095FT in the desired location, and install
flange or flange/adaptor bolts.
a.Finger-tighten the bolts.
b.Torque the bolts to the initial torque value using a cross-pattern
(see Table 2-2).
c. Torque the bolts to the final torque value using the same cross-
pattern.
TABLE 2-2. Bolt Installation Torque
Values.
When installing the transmitter to one of the mounting brackets, torque
the mounting bracket bolts to 125 in-lb.
3. Make Process
Connections
3. Connect the transmitter to the process.
For explosion-proof installations, installation location must
be made in accordance with Rosemount drawing 03095-
1025 or 03095-1024.
For instrinsically safe installations, installation location must
be made in accordance with Rosemount drawings
03095-1020 and 03095-1030; or 03095-1021 and
03095-1031.
Only use bolts supplied with the Model 3095FT or sold by
Rosemount Inc. as a spare part to the Model 3095FT.
Unauthorized parts can affect product performance and
may render the instrument dangerous.
Bolt Material Initial Torque Value Final Torque Value
Carbon Steel (CS) 300 in-lb 650 in-lb
Stainless Steel (SST) 150 in-lb 300 in-lb
Process leaks can cause death or serious injury. All four
flange bolts must be installed and tight before applying
pressure, or process leakage will result. When properly
installed, the flange bolts will protrude through the top of the
module housing. Attempting to remove the flange bolts
while the transmitter is in service will result in leakage of the
process fluid.
