JUNCTION BOX
1. Pull wire through the wall and out of the junction box, leaving about 6 inches
free.
2. Pull the wire through the hole in the base plate.
3. Secure the plate to the box using the #6-32 x 1/2” mounting screws provided.
4. Terminate the unit according to the Termination Guidelines section.
5. Attach Cover by latching it to the top of the base, rotating the cover down and
snapping it into place.
6. Secure the cover by backing out the lock-down screws using a 1/16” allen
wrench until they are ush with the bottom of the cover.
DRYWALL MOUNTING
1. Place the base plate against the wall where you want to mount the sensor.
2. Use a pencil to mark the two mounting holes and the area where the wires will
come through the wall.
3. Drill two 3/16” holes in the center of each marked mounting hole. Insert a drywall anchor into each hole.
4. Drill one 1/2” hole in the middle of the marked wiring area.
5. Pull the wire through the wall and out of 1/2” hole, leaving about 6” free.
6. Pull the wire through the hole in the base plate.
7. Secure the base to the drywall anchors using the #6 x 1 inch mounting screws provided.
8. Terminate the unit according to the Termination Guidelines section.
9. Attach cover by latching it to the top of the base, rotating the cover down and snapping it into place. Secure the
cover by backing out the lock-down screws using a 1/16” Allen wrench until they are ush with the bottom of the
cover.

NOTE: In a wall-mount application, the wall temperature and the temperature of the air within the wall cavity can cause
erroneous readings. The mixing of room air and air from within the wall cavity can lead to condensation, erroneous
readings and premature failure of the sensor. To prevent these conditions, seal the conduit leading to the junction box
and use BAPI’s adhesive backed, foam insulating pad centered over the hole (order part number BA/FOAMBACK).

Termination
BAPI recommends using twisted pair of at least 22AWG and sealant lled connectors for all wire connections. Larger
gauge wire may be required for long runs. All wiring must comply with the National Electric Code (NEC) and local codes.
Do NOT run this device’s wiring in the same conduit as AC power wiring of NEC class 1, NEC class 2, NEC class 3 or
with wiring used to supply highly inductive loads such as motors, contactors and relays. BAPI’s tests show that uctuating and inaccurate signal levels are possible when AC power wiring is present in the same conduit as the signal lines. If
you are experiencing any of these difculties, please contact your BAPI representative
BAPI recommends wiring the product with power disconnected. Proper supply voltage, polarity, and
wiring connections are important to a successful installation. Not observing these recommendations may
damage the product and will void the warranty.

NOTES
For Common Ground (CG) units, the GND (Common) terminal is
common beween the POWER, OUT A, and OUT B.
For Differential Ground (DF) units, OUT A and OUT B are the Setpoint Outputs, and TEMP + and TEMP – are the Thermistor or RTD
sensor outputs.
