Installing the RTBUS-27xl
To install the RTBUS-27xl perform the following steps:
1. Drill a hole in the table (see Drilling a Hole in the Table on page 6).

3. Connect the cables (see Connecting the Cables on page 7).
4. Secure the unit to the table (see Mounting the RTBUS-27xl in the Table on page 9).
Drilling a Hole in the Table
To drill an opening in the table:
1. Using any standard cup bit drill with a diameter ranging from 111mm to 114mm (4.37in to
4.49in), drill a hole in the table in the desired location.
The thickness of the table should be 3in (76mm) or less.
2. Clean the table surface.
Take care not to damage the table. Kramer AV is not responsible for any damage caused to
the table.
Installing the Power Socket
Figure 3 shows an example of the Universal power socket housing which is one of the
optional power sockets for the RTBUS-27xl, see Power Socket Options on page 5.
To install the power socket (purchased separately):
1. Close the RTBUS-27xl lid.
2. Carefully insert the power socket housing so that
the power socket fits into the power socket
opening on the connecting surface and the four
standoffs fit the four screw holes on the
RTBUS-27xl.
When positioned correctly, the IEC socket faces
forward.
3. Screw the four screws included in the power
socket kit into the designated holes to fix the
power socket housing in place.
4. Unscrew the power connector lock.
5. Connect the IEC power cord to the IEC socket.
