Installation
Installation and mounting
1. Most of our products are intended for various methods of installation or mounting (panel mounting, bracket
mounting, ceiling/wall mounting etc.); for details, please see the relevant mechanical drawings.
2. Adequate ventilation is a necessary prerequisite for the life of the product. The air inlet and outlet openings must
definitely be kept clear; coverings which restrict ventilation are not permissible.
3. Generally, do not install the unit in a horizontal position (laying down), as this will cause heat to build up inside the
unit which will damage the LCD Panel. To prevent this problem werecommend installing the unit in a vertical
position (±30 degrees) to improve the airflow through the unit.
4. 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.
5. Exposure to extreme 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.)
6. Space necessary for ventilation, for cable inlets, for the operating procedures and for maintenance, must be
provided.
7. If the push buttons of the product are not illuminated, an external, dimmable illumination (IEC 60945 Ed. 4, 4.2.2.3,
e.g. Goose neck light) is required for navigational use. The illumination shall be dazzle-free and adjustable to
extinction.
8. Information about necessary pull-relievers for cables is indicated in the Physical Connection section of this manual.
Attention must be paid to this information so that cable breaks will not occur, e.g. during service work.
9. Do not paint the product. The surface treatment influences on the excess heat transfer. Painting, labels or other
surface treatments that differ from the factory default, might cause overheating. Painting could also affect
TEMPEST performance, as grounding could be affected.
10. 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 display 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.
4. Units which are to be used on the bridge wing must be installed inside the “wing control console” protected against
the weather. In order to avoid misting of the viewing screen, a 25 ... 50 W console-heating (power depending on the
volume) is recommended.
5. When selecting the site of a display unit, the maximum cable lengths have to be considered.
