General mounting instructions
1. The useful life of the components of all Electronics Units generally decreases with increasing ambient
temperature; it is therefore advisable to install such units in air-conditioned rooms. If there are no such
facilities, these rooms must at least be dry, adequately ventilated and kept at a suitable temperature in order
to prevent the formation of condensation inside the unit.
2. With most Electronic Units, cooling takes place via the surface of the casing. The cooling must not be
impaired by partial covering of the unit or by installation of the unit in a confined cabinet.
3. In the area of the wheel house, the distance of each electronics unit from the magnetic standard compass or
the magnetic steering compass must not be less than the permitted magnetic protection distance. This
distance is measured from the centre of the magnetic system of the compass to the nearest point on the
corresponding unit concerned. The exact distance is often mentioned in the specific product specifications.
4. Transportation damage, even if apparently insignificant at first glance, must immediately be examined and be
reported to the freight carrier. The moment of setting-to-work of the equipment is too late, not only for
reporting the damage but also for the supply of replacements.
5. The classification is only valid for approved mounting brackets provided by Hatteland Technology. The unit
shall be mounted stand-alone without any devices or loose parts placed at or nearby the unit. Any other type
of mounting might require test and re-classification.
6. Additional rules may apply to certain procedures where the symbols and are present. For more
information, review “IEC62368 policy for Hatteland Technology product” section later in this manual.
Cables
Use only high quality shielded signal cables. For RGB/DVI cables use only cables with separate coax for Red, Green
and Blue.
