Rosemount 3095 MultiVariable

Optional Transient 
Protection Terminal 
Block

The transient terminal block can be ordered as an installed option (Option 
Code T1 in the transmitter model number) or as a spare part to retrofit existing 
3095 transmitters in the field. See “Spare Parts List” on page A-14.

Installation

When the transient protection terminal block is ordered as a spare part, it 
must be installed in place of the standard terminal block inside the transmitter 
housing. See “Removing the Electrical Housing” on page 5-8.

NOTE

The transient protection terminal block provides transient protection only if the 
transmitter housing is properly grounded. See “Grounding the Transmitter 
Housing” on page 2-14.

Performance

The transient protection terminal block increases the ability of the 3095 
transmitter to withstand electrical transients induced by lightning, welding, or 
heavy electrical equipment. With the transient protection block installed, the 
3095 transmitter meets the standard performance specifications as outlined in 
this product manual. In addition, the transient protection circuitry meets IEEE 
Standard 587, Category B and IEEE Standard 472, Surge Withstand 
Capability.

INSTALLATION 

Equipment

The following equipment and tools are not provided with the 3095 transmitter. 
Be sure to review the list prior to field installing the transmitter. 

•

Installation tools

•

Field wire between the power supply and the 3095 transmitter

•

Barriers or seals required for hazardous locations 

•

Conduit

•

2-in. (50.8 mm) mounting pipe or saddles

•

Power supply 

•

3- or 5-valve manifolds, unless otherwise specified

•

Impulse piping

•

Tie  wraps 

Use the following steps to successfully install the 3095 transmitter.

1.

Review the installation considerations described on “Considerations” 
on page 2-4 to determine the location for the 3095 transmitter. 

Mount Transmitter and 
Install Bolts

2.

Mount the 3095 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.
