Specifications subject to change without notice.
Terminations
Note1: The termination screws should be turned fully Counter Clockwise (CCW) to open the jaws fully. Then insert the field wire and turn
the screws Clock Wise (CW) to pinch the wire fully closed. If the jaws are left partially open, the inserted wire may be on bottom of, instead
of inside, the jaws causing a poor connection.
BAPI recommends using twisted pair of at least 22AWG and sealant filled 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 recommends against wiring the sensor with power applied as accidental arcing may damage the product and void the warranty.

NOTE: Common Ground Option (CG) OVR2, SEN2, and SET2 are connected together internally.
Differential Ground Option (DF) All terminals are independent.
4 to 20 mA Termination
Terminal Function
OVR1 & OVR2 Override Output (Dry Contact Switch). If unit is in common ground
(-CG), OVR2 is internally connected to SET2 & SEN2.
SET1 & SET2 Setpoint output. If unit is common ground (-CG), SET2 is internally con-
nected to OVR2 & SET2.
SEN1 & SEN2 Sensor Output (Resistive Output). If common ground (-CG), SEN2 is in-
ternally connected to OVR2 & SET2. (Semiconductor SEN1=+, SEN2=-)
EXT-OVR
Allows remote control of the LCD indicator for occupancy, and is acti-
vated by logic LOW or power supply ground at this terminal.

Mounting
Mounting hardware is provided for both junction box and drywall installation (junction box installation shown).
Junction Box
1. Pull the wire through the wall and out of the junction box, leaving about six 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 inch mounting screws provided.
4. Terminate the unit according to the guidelines in the
Termination 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 flush with the bottom of the cover.
Drywall Mounting
1. Place the base plate against the wall where you want to mount the sensor.
2. Using a pencil mark out 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 the 1/2” hole, leaving about six inches 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 guidelines in the
Termination section.
9. Attach cover by latching it to the top of the base, rotating the cover down and snapping it into place.
10. Secure the cover by backing out the lock-down screws using a 1/16” Allen wrench until they are flush with the bottom of the cover.
Fig 2: Mounting to a Junction Box
NOTE: In any wall-mount application, the wall temperature and the temperature of the air within thewall 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 or fill the box with insulation.
