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 for panel cutout
dimensions and product dimensions. For Panel/console installations, please use screws as specified in the
Contents of Package chapter.
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. Do not install the unit in a horizontal position (laying down), as this will cause heat to build up inside the display
which will damage the LCD Panel. To prevent this problem we recommend installing the unit in a vertical position
(±40 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 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. Information about necessary pull-relievers for cables is given in the installation drawings. Attention must be paid to
this information so that cable breaks will not occur, e.g. during service work.
8. Do not paint/re-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.
9. 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.
Ergonomics
1. Adjust the unit height so that the top of the screen is at or below eye level. Your eyes should look slightly
downwards when viewing the middle of the screen.
2. Adjust screen inclination to remain gaze angle to the centre of the screen approximately perpendicular to the line of
gaze.
3. When products are to be operated both from a sitting position and from a standing position, a screen inclination of
about 30° to 40° (from a vertical plane) has turned out to be favourable.
4. Depending on solution, the units may be provided with optical bonding technology to reduce reflections and are
viewable in direct sun light, but as a general rule the units at the bridge wing area is recommended to be installed
or mounted by suitable alignment or bulkhead / deckhead mounting in such a way that reflections of light from the
front pane of the display are not directed into the observer’s viewing direction.
5. The use of ordinary commercial filter plates or filter films is not permitted for items of equipment that require
approval (by optical effects, “aids” of that kind can suppress small radar targets, for example).
