Installing the RKP Computer

The RKP computers come preinstalled with two rack-mounting ears. To mount the computer on to a rack, do the following:

Step 1 : If the mounting ears are not installed, use four screws each to attach the mounting ears on both sides of the computer.

Step 2:
Place the RKP on a rack and use another four screws to secure the rack-mount ears to the rack.

The second set of four screws needs to be purchased separately. Refer to the figure on the right for the specifications.

NOTE This computer is intended to be installed only in an area with restricted access. In addition, for safety reasons, the computer should be installed and handled only by qualified and experienced professionals.

Connecting the Power

The RKP computers are provided with 2-pin power input connectors in a terminal block on the front panel. Insert the power-cord wires into the connectors and tighten them to secure the wires in place. Plug in the power cable to a power source. The power LED 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.

ATTENTION
This product is intended to be supplied by a Listed Power Supply with output marked LPS and rated to deliver 12 VDC at a maximum of 5.4 A, or 24 VDC at a maximum of 2.6 A, and minimum Tma=60˚C. If you need assistance with purchasing a power adapter, contact the Moxa technical support team.

ATTENTION
Before connecting the RKP computer to the DC power inputs, ensure that the DC power source voltage is stable.

• The wiring for the input terminal block shall be installed by qualified and experienced professionals.
• Wire Type: Cu, FW2
• Use 18-12 AWG wire size and a torque value of 0.5 Nm.
• Use only one conductor in a clamping point between the DC power source and the power input.

NOTE If using Class I adapter, the power cord adapter should be connected to a socket outlet with an earthing connection or the power cord and adapter must comply with Class II construction.

NOTE For surge protection, connect the grounding connector located below the power connector with the earth (ground) or a metal surface.
An 18 AWG cable size conductor must be used when the connection to the external grounding screw is utilized. The heat sink is grounded to the chassis by an internal screw.

Warning

Connecting Displays

The RKP computer comes with an HDMI connector and a VGA connector located on the front panel for connecting audio or video devices.

NOTE Use HDMI-certified cables for a reliable audio or video connection.

Communication Connections
