4.
Align the template over the cable hole with the reference point facing in the
correct direction. Mark the positions of the two mounting holes.
5.
Drill two pilot holes for the mounting screws (provided).
6.
Disassemble the SMA-1 by undoing the locking nut and removing the
remaining parts from the conduit.
7.
Place the conduit (with base) over the cable hole, with the tooth pointing in
the direction of the reference point.
8.
Place the insulation disk over the conduit.
9.
Place the swivel disk over the insulation disk so that the mounting holes align
with the pilot holes drilled in step 5.
10.
Secure the swivel disk to the table using two screws through the mounting
holes.
11.
The unit ships with one set screw inserted into the swivel disk (see figure 3).
If a different orientation is required, remove that set screw and insert one or
two others into the appropriate stopping point holes, using the hex key.
CAUTION: Turn the set screw until the top of the screw is flush with the top
of the calibration disk. If the set screw is not fully inserted into
the stopping point hole, it will damage the bottom surface of
the surface mount box.
Attaching a Mounting Box
Figure 3 shows how to mount the SMB-303.
1.
If necessary, remove any devices that are
mounted in the box.
2.
Place the base of the box over the conduit and
align it so that the front of the box faces the
reference point.
3.
Place the backing plate over the conduit so
that it sits on the floor of the mounting box.
4.
Tighten the locking nut to attach the box to
the base of the SMA-1. The nut must be tight
enough to prevent the box from rocking
backwards and forwards. Do not overtighten.
5.
Check that the assembly can rotate to the
stopping point in each direction.
6.
Run cables and mount a device in the
mounting box, as described in the user guides
for the box and the installed device. These
guides can be downloaded from the Extron
