Wire sensor as shown below in Figure 5. Keep sensor
wiring separate from power wiring. For best EM /RF pro-
tection, use shielded output signal cable in an earth-
grounded metal conduit. Refer to the sensor instruction

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 instruc-
tion 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 pre-
pare unterminated cable for use, follow the instructions in
the sensor instruction manual.

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.

1. Although the analyzer is suitable for outdoor use, do
not install it in direct sunlight or in areas of extreme
temperatures.
2. nstall 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.
