WIRING
Wire sensor as shown below in Figure 2. Keep sensor wiring separate from power wiring. For best EMI/RFI protection, use shielded output signal cable in an earth-grounded metal conduit. Refer to the sensor instruction manual for more details.

FIGURE 3. Power Supply/Current Loop Wiring for Model 5081T-FF/FI
WIRING THROUGH A JUNCTION BOX
The sensor can be wired to the analyzer through a remote junction box (PN 23550-00). Wire the extension cable and sensor cable point-to-point. Refer to the sensor instruction manual for more details.
Factory-terminated (PN 23747-00) and unterminated (PN 9200275) connecting cable are available. The use of fac- tory-terminated cable is strongly recommended. To prepare unterminated cable for use, follow the instructions in the sensor instruction manual.
For maximum EMI/RFI protection, the outer braid of the sensor cable should be connected to the outer braided shield of the extension cable. At the instrument, connect the outer braid of the extension cable to earth ground.
POWER WIRING
For general purpose areas, wire power as shown in Figure 3.

UNPACKING AND INSPECTION
Inspect the shipping container. If it is damaged, contact the shipper immediately for instructions. Save the box. If there is no apparent damage, unpack the container. Be sure all items shown on the packing list are present. If items are missing, notify Rosemount Analytical immediately.
ROTATING THE DISPLAY
The Model 5081T-FF/F1 display can be rotated 90° left or right. Disengage the cover lock and remove the front cover. Remove the three screws holding the PCB stack and gently lift the display board. Do not disengage the ribbon cable between the display board and the CPU board. Rotate the display. The black infrared sensor will be at the top of the display.
INSTALLATION
See Figure 4.
1.Although the analyzer is suitable for outdoor use, do not install it in direct sunlight or in areas of extreme temperatures.
2.Install the analyzer in an area where vibrations and electromagnetic and radio frequency interference are minimized or absent.
3.Keep the analyzer and sensor wiring at least one foot from high voltage conductors. Be sure there is easy access to the analyzer.
4.The conduit connections on the sides of the 5081 housing should be sealed to prevent moisture from entering the enclosure.
5.The transmitter must not be mounted with both conduit openings at the top.
