General Installation Recommendations
Installation and mounting of computers
1. Units may be intended for various methods of installation or mounting (rack mounting, panel mounting,
bracket mounting, ceiling/wall mounting); for details, please see the relevant mechanical drawings.
2. Adequate ventilation is a necessary prerequisite for the life of the unit. The air inlet and outlet openings must
definitely be kept clear; coverings which restrict ventilation are not permissible. The product might be without
any ventilation aperatures which means pt.2 does not apply.
3. Exposure to direct sunlight can cause a considerable increase in the temperature of the unit, and might under
certain circumstances lead to overtemperature. This point should already be taken into consideration when
the bridge equipment is being planned (sun shades, distance from the windows, ventilation, etc.)
4. Space necessary for ventilation, for cable inlets, for the operating procedures and for maintenance, must be
provided.
5. To further improve the cooling of the unit we recommend installing Cooling Fans underneath blowing upwards
into the unit air inlet. This may be required in high temperature applications and also when there is reason to
expect temperature problems due to non-optimal way of mounting.
6. This Product shall be grounded to protective Earth. For AC Power cables this is done trough the ground wire
in the connector, for DC input the ground bolt shall be used. A shorter and thicker cable gives better
grounding. A 6mm² is recommended, but a 4mm² or even 2.5mm² can be used for this purpose.
7. Expose to heavy vibration and acoustic noise might under certain circumstances affect functionality and
expected lifetime. This must be considered during system assembly and installation. Mounting position must
carefully be selected to avoid any exposure of amplified vibration.
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 Display. 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.
