Installation Recommendations

Installation and mounting of Display Monitors

1. Most of our displays monitors 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 display. The air inlet and outlet
openings must definitely be kept clear; coverings which restrict ventilation are not permissible.
3. Do not install the monitor 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 monitor in a vertical position (±30 degrees) to improve the airflow through the
monitor.
4. 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.)
5. Space necessary for ventilation, for cable inlets, for the operating procedures and for
maintenance, must be provided.
6. To further improve the cooling of the monitor we recommend installing Cooling Fans underneath
the monitor blowing upwards into the monitor 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(Ref.2-5).
7. If the push buttons of the display are not illuminated, an external, dimmable illumination
(IEC 60945, 6.5.c, e.g. Goose neck light is required for navigational use.
8. 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.

Ergonomics

1. Adjust the monitor 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 screen 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. The brightness of monitors is limited. Sunlight passing directly through the bridge windows - or its
reflection - which falls upon the screen workplaces must be reduced by suitable means
(negatively inclined window surfaces, Venetian blinds, distance from the windows, dark colouring
of the deckhead)
