Installation
LCD display rotation
In addition to housing rotation, the optional LCD display can be rotated in 90° increments by squeezing
the two tabs, pulling out, rotating and snapping back into place.
Note
If LCD display pins are inadvertently removed from the feature board, re-insert the pins before snapping
the LCD display back into place.
Field terminal side of housing
Mount the transmitter so the terminal side is accessible. Clearance of 0.75-in. (19 mm) is required for
cover removal. Use a conduit plug in the unused conduit opening if the optional Process Temperature
Input is not installed.
Feature board side of housing
Provide 0.75-in. (19 mm) of clearance for units without an LCD display. Three inches of clearance is
required for cover removal if an LCD display is installed.
Cover installation
Always ensure a proper seal by installing the housing covers so that metal contacts metal in order to
prevent performance degradation due to environmental effects. For replacement cover O-rings, use
Rosemount O-rings (part number 03151-9040-0001).
Conduit entry threads
For NEMA
®
4X, IP66, and IP68 requirements, use thread seal (PTFE) tape or paste on male threads to
provide a watertight seal.
Cover jam screw
For transmitter housings shipped with a cover jam screw, as shown in Figure 3-3 on page 70, the screw
should be properly installed once the transmitter has been wired and powered up. The cover jam screw is
intended to prevent the removal of the transmitter cover in flameproof environments without the use of
tools. Follow these steps to install the cover jam screw:
1. Verify the cover jam screw is completely threaded into the housing.
2. Install the transmitter housing covers and verify that metal contacts metal in order to meet
flameproof/explosion-proof requirements.
3. Using an M4 hex wrench, turn the jam screw counterclockwise until it contacts the transmitter cover.
4. Turn the jam screw an additional
1
/2 turn counterclockwise to secure the cover. Application of
excessive torque may strip the threads.
5. Verify the covers cannot be removed.
