desired position, screw and tighten it in place using the height adjustment
screws (supplied with the inner frame).
5.3 Cutting an Opening in the Table
To cut an opening in the table:
1. Place the included cut out template (that is included with your TBUS-4xl) on
the surface of the table exactly where you want to install the TBUS-4xl.
2. Attach the template to the table with the included screws (if using the cut out
template).
3. Following the inside edge of the template, cut a hole in the table surface
with a sabre or keyhole saw according to the dimensions shown in Figure 4
(not to scale).
Figure 4: Cut out Dimensions

4. Unscrew and remove the template from the surface of the table and clean
the table surface.
Take care not to damage the table.
If needed, you can download a full-scale template from our Web site.
5.4 Inserting the TBUS-4xl through the Cut Out Opening
To install TBUS-4xl in the opening:
1. Remove the protective rubber guard from around the outer rim of the
TBUS-4xl housing. Beware of the sharp edge!
2. Carefully insert the unit into the prepared opening (see Figure 5).
3. Take the support brackets under the table and place them into the support
bracket grooves on both sides of the unit (see Figure 2, item 7).
4. Verify proper alignment of the unit before tightening the mounting screws.
5. Tighten both mounting butterfly screws upward until they reach the table
surface (from underneath). Tighten firmly (see Figure 5).
6. Tighten the locking butterfly screws downward until tight against the
mounting bracket.

5.5 Connecting the Cables
When replacing blank inserts with connector inserts (for example, VGA, audio,
HDMI and so on):
1. Insert the cables to their appropriate connectors from underneath.
2. Secure the cables to the tie holes using the included self-locking ties.
Do not secure the cables too tightly or too loosely. Leave a small amount of
slack.
After the TBUS-4xl is connected to mains power and the proper cables, it is ready for
use.
5.6 Inserting the Pass-through Cables
To insert the pass-through cables, for example, to connect a laptop, do the
following (see Figure 3):
1. Remove the two screws attaching the split pass-through bracket.
2. Remove the split grommet.
3. Insert the cable through the rectangular opening.
4. Open the split grommet slightly and insert the required cables.
5. Place the split bracket around the grommet and position this assembly over
the Inner Frame.
6. Place the two screws appropriately and tighten the split bracket together
with the grommet and inserted cables to the inner frame.
7. Insert the self-locking ties through the tie holes to secure the cables to the
inside walls of the enclosure.
