2. Use the screwdriver to carefully pry each bottom corner if
necessary. Tip the cover away from the base and place it aside
as shown Figure 3.

3. The PCB must be removed from the base to access the
mounting holes. Follow usual anti-static procedures when
handling the PCB and be careful not to touch the sensors. The
PCB is removed by pressing the enclosure base to unsnap the
latch near the bottom edge, and then the PCB can be lifted out of
the base as shown in Figure 4. Sit the PCB aside until the base
is mounted on the wall.

For added protection, place the PCB in the supplied
anti-static bag.
4. Mount the base by screwing to an electrical box or directly to the
wall as shown in Figure 5. The mounting hole locations are
shown in Figure 14 on Page 7.

5. After the base is screwed to an electrical box or the wall using
the appropriate holes, remove the PCB from the anti-static bag,
feed connection wires through center hole and place the top of
PCB into the PCB holders on the baseplate and snap the bottom
of PCB into place as shown in Figure 6.

6. Make wire connections as per the Wiring and install decorative
cover by placing the top of the cover into the cover holder on the
top of the baseplate and snapping the bottom into place as
shown in Figure 7. Tighten security screw with a Phillips
screwdriver.

Wiring
Use 22 AWG shielded wiring for all connections and do not locate the
device wires in the same conduit with wiring used to supply inductive
loads such as motors. Disconnect the power supply before making any
connections to prevent electrical shock or equipment damage. Make all
connections in accordance with national and local codes.
Connector layout is shown in Figure 8. Diagram shown includes all
options. If option is not ordered, connector will not be present.

Connect the positive dc voltage or the hot side of the ac voltage to the
terminal marked POWER. The power supply common is connected to
the terminal marked COMMON as shown in Figure 9. The device is
reverse voltage protected and will not operate if connected backwards.
This device has a half-wave type power supply so the power supply
common is the same as the output signal common. Therefore, several
devices may be connected to one power supply and the output signals
all share the same signal common. Use caution when grounding the
