Important notes for siting and installation
Place of installation
Every electronic device generates some heat. The rise in temperature, however,
lies within safe limits. Nevertheless, this does not rule out the possibility of slight
colour changes to sensitive furniture surfaces and veneers over time due to the
constant effect of heat.
In conjunction with treated furniture surfaces, the unit‘s rubber feet can likewise
give rise to changes in colour. Where necessary, place the unit on a suitable pad.
Ventilation
The heat that is generated in this unit is dissipated quite adequately. Never install
the receiver in a cabinet, shelf or rack with inadequate ventilation. Never close-off
the openings on the unit that are intended for heat dissipation.
Do not place objects on top of the unit. Maintain a clearance of at least 10 cm
above the unit so that the heat generated within the unit is convected away without
obstruction.
Mains voltage
Run the receiver only from a mains voltage of 230V / 50Hz.
The unit is not to be connected to the mains until after all the installation work has
been completed.
Humidity
Protect the unit against humidity, drips and splashes.
Solar radiation/heat
Do not place the receiver close to radiators nor expose it to direct sunlight.
Grounding
The parabolic antenna is to be grounded in accordance with regulations. Here, the
relevant German VDE regulations (or equivalent) are to be observed.
LNB supply voltage
If the feeder system (LNB) is supplied with an external supply voltage and the LNB
supply voltage is not used for polarity switchover (e.g. Kathrein single-cable feeder
system UAS 330), the receiver‘s LNB supply must be set to “OFF“ (refer to section:
“Initial settings, LNB supply voltage“).
There is a risk that the receiver may suffer damage if the change-over is not carried
out..
