Installing the HT20470 Processor Unit
The Processor Unit can be installed inside a console, inside a suitable cabinet, in a 19" rack or on a desk. The Processor Unit does not contain any fans. It will be very warm, even during normal operation. Make sure that adequate ventilation is available to avoid overheating.
Prerequisites
You must be equipped with a standard set of tools. This tool set must comprise the normal tools for electronic and electromechanical tasks. This includes different screwdriver types, pliers, spanners, a cable stripper, a soldering iron, etc. Each tool must be provided in various sizes. We recommend that all tools are demagnetized to protect your equipment.
A suitable location for the Processor Unit must be defined before installation. Observe the compass safe distance.
Context

Remove the two plastic blocks located behind each side of the front panel. Fasten the two mounting brackets to the space made available.
Note
The Processor Unit does not contain any fans. It will be very warm, even during normal operation. This is by design. Airflow around the unit will significantly increase the effect of the heat sinks and thereby also the lifetime of the unit. Such an air flow is highly recommended. The computer has been tested and verified with ambient temperatures up to 50 degrees Celsius. A lower ambient temperature is however positive for the its lifetime.
Procedure
1 Prepare the location and the necessary tools.
2 Observe the installation requirements.
a Depending on its physical properties, install the computer inside a console, in a cabinet or 19” rack, or on a desk.
b Choose a position to fit the available cable lengths between the computer and the other units it connects to.
c Observe the compass safe distance.
d Make sure that enough space is made available for maintenance purposes.
e Make sure that adequate ventilation is available to avoid overheating.
f Make sure that the installation method allows for the physical vibration, movements and forces normally experienced on a vessel.
Note
To allow future maintenance, you must mount the unit with its cables and connectors available for easy access.
3 Make sure that the chosen location meets the installation requirements.
4 Provide ample space around the computer.
You must be able to reach and use the front and rear mounted connectors and on/off switches. It is also important that you allow for easy access to all the computer cables, and enough space for inspection, maintenance and parts replacement. If relevant: Make sure that the space allows you to open the computer for unobstructed access to its internal parts.
Note
Make sure that you can access both the rear and front side of the computer after it has been installed.
