MOUNTING
(Continued)
Now fasten and insert (2) screws #8 x 3/4" TEK
(provided and recommended) through the
mounting holes in the flange and tighten until
the unit is held firmly to the duct. Make sure the
foam pad is tight to the duct to eliminate any
possible air leaks. Refer to the
Wiring Instruc-
tions
(p. 2-3) to make necessary connections.
Note:
All enclosures have the foam pad attached.
For the “DO” (no enclosure), the foam pad is
included, but not installed. The foam pad must be
installed prior to mounting.

WIRING INSTRUCTIONS
Open the cover of the enclosure. ACI recommends 16 to 26 AWG twisted pair wires or shielded cable for all
sensors. Signal wiring must be run separate from low and high voltage wires (24/120/230VAC). All ACI thermis-
tors and RTD temperature sensors are both non-polarity and non-position sensitive. All thermistor type units
are supplied with (2) flying lead wires, and all RTD’s are supplied with (2) or (3) flying lead wires – see
FIGURE
4
(below). The number of wires needed depends on the application.
