6. Rotate the mounting base until one of the arrows on the
base points up. If necessary, reposition the cover screw
above the arrow. Place the base against the wall, and mark the
screw holes using the base as a template.
7. Drill two 8 mm (5/16 in.) holes at the markings.
8. Insert the hollow plastic wall anchors (Figure 84), position
the base, and then drive the two pan-head tapping screws.
9. Pull the wiring through the mounting base.
10. Remove terminal block and wire to the appropriate terminals as
shown in “Wiring”.
11. Install terminal block onto sensor with terminal 6 next to the
edge of sensor.
12. Replace the sensor and tighten the cover screw.
13. Replace the two end-caps on the mounting base.

Performing Surface Mounting Using Small Base
To perform surface mounting using the small base (Figure 85):
1. Slide the desired cover slider insert onto the sensor until it snaps
into place.
2. Remove the two end-caps from the mounting base.
3. Remove the cover screw using a 1.5 mm (1/16 in.) Allen
wrench and discard it. Remove the sensor.
4. Remove and discard the terminal block from inside the sensor.
5. Drill a 35 mm (1-3/8 in.) hole in the surface where the sensor will
be mounted.
6. Pull the cable or wiring through the hole.
7. Place the small base against the wall (with the arrow on
the base pointing up) and mark the screw holes using the
base as a template.
IMPORTANT
Figure 83 – Surface Mounting Using Large Base
The MicroTech II Wall-Mounted Sensor allows for two mounting
methods: wall-box mounting and surface mounting.
Note: Wall-box mounting requires the large mounting base.
Use either the large or small mounting base for surface mounting.
Performing Wall-box Mounting
To perform wall-box mounting (Figure 82):
1. Slide the desired cover slider insert onto the cover until it
snaps into place.
2. Remove the two end-caps from the mounting base.
3. Loosen the cover screw using a 1.5 mm (1/16 in.) Allen
wrench and remove the sensor.
4. Pull the cable or wiring through the wall-box and mounting base.
5. Rotate the mounting base until one of the arrows on the
base points up and the screw openings in the base align
with the threaded holes in the wall-box. If necessary, reposition
the cover screw above the arrow.
6. Fasten the base to the wall-box with the No. 6-32 x 1 in.
screws provided.
7. Remove terminal block and wire to the appropriate terminals as
shown in ”Wiring”.
9. Replace the sensor and tighten the cover screw.
10. Replace the two end-caps on the mounting base.
