Webster IRP 4100 Installation Manual page 19

The accessory compartment on the left side of the console is
planned primarily for access to the inside of the power control panel,
but it can also be used for some accessory equipment of your own
choosing.
The power control panel, shown below, has IEC-type cable
connectors on the inside as well as the outside, and there are AC
power drop cords running inside from the panel to both the PC and
accessory compartments.
You will need to connect various cables to the IRP 4500 power
control panel on the left hand side of the console, to the projector in
the rear of the unit, and to your host computer. Cables may run
inside or outside the console unit, to or from the projector, and to or
from your host computer.
Cable access openings to the inside of the console are located above
and to the right of the power control panel. There are additional
openings at bottom rear of the console on either side, at either end
of the built-in cable tray that runs between the right and left-hand
sides of the console.
You have your choice as how to route your cables. It is usually better
to group and route cables together, depending on their type, source,
and destination. Use the built-in cable tray whenever possible.
When you are satisfied with the final organization and routing of your
cables, you may want to use tie wraps to provide strain relief and
maintain order for the cables within the console unit.
