Mechanical Installation
Upon delivery, undertake visual inspection of the package contents for signs of transport damage and
verify the information on the type plate sticker against your order. Do not open the device housing.
For longer storage of the device, select a dry and clean environment. Make sure that the device is not
stored near strong heat sources and that no metal chippings or other dirt can get into the device or its
connectors.
The SCU is mounted on a horizontal or vertical surface using four screws (max. diameter 4.0 mm) not
included in the package. The hole positions can be taken from Figure 4-1. If you are using fixed female
threads in the mounting surface instead of nuts, provide a minimum thread length of 4 mm. Always
secure your mounting joint. The Front and Display Panels require a rounded rectangular cutout (see
Figure 4-6 and Figure 4-8 ) and are mounted on the aircraft instrument panel using four M4 Philips
headed screws included in the package. Three-dimensional CAD-models of all units are available on
request.
As waste heat is dissipated via free convection, leave at least a 5 mm gap from the exterior surfaces
(excluding the mounting face) to any other object. Forced cooling is not necessary.
The installation must be in accordance with the appropriate guidelines approved by the respective
aviation authority. The person installing the device is responsible for compliance with all applicable
legislation.
