General Installation Recommendations
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.
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.
6. 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.
7. The grounding screws of the units must be connected to the body of the ship (ground); the wire used should have a
cross sectional area of at least 6 mm 2 .
8. 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.
9. 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.
