General Installation Recommendations

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.The brightness of displays 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)

5.Units in the bridge wing area must 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.

6.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).

General mounting instructions

-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.

-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.

-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.

-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.

-When selecting the site of a display unit, the maximum cable lengths have to be considered.
