General Installation Recommendations
Installation
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
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.
6. The impairment of read-out from a display screen by direct light from lamps or the sun must be avoided. Rear
windows must be blacked out by means of roller blinds or Venetian blinds.
7. Disturbing reflections on the screen of a display caused by pilot lamps and illuminated signs must be prevented by
suitable measures (screening or relocating).
8. When a product is being installed, the surface base or bulkhead must be checked to ensure that it is flat in order to
avoid twisting of the unit when the fixing screws are tightened, because such twisting would impair mechanical
functions. Any unevenness should be compensated for by means of spacing-washers.
9. 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.
10. 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.
11. 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.
