Installing the V2403C
The V2403C computer comes with two wall-mounting brackets. Attach
the brackets to the computer using four screws on each side. Ensure
that the mounting brackets are attached to the V2403C computer in the
direction shown in the following figure.
The eight screws for the mounting brackets are included in the product
package. They are standard IMS_M3x5L screws and require a torque of
4.5 kgf-cm. Refer to the following illustration for details.
Use two screws (M3*5L standard is recommended) on each side to
attach the V2403C to a wall or cabinet. The product package does not
include the four screws required for attaching the wall-mounting kit to
the wall; they need to be purchased separately. Ensure that the
V2403C computer is installed in the direction shown in the following
figure.

Connecting the Power
The V2403C computers are provided with 3-pin power input connectors
in terminal block on the front panel. Connect the power cord wires to
the connectors and then tighten the connectors. Push the power button.
The Power LED (on the power button) will light up to indicate that
power is being supplied to the computer. It should take about 30 to 60
seconds for the operating system to complete the boot-up process.
