MODEL 5081T-FF/FI WIRING
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 2. Wiring Model 5081T-FF/FI

MODEL 5081T-FF/FI WIRING
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 factory-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.

INSTALLATION
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
