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.
- 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.
- Disturbing reflections on the screen of a display caused by pilot lamps and illuminated signs must
be prevented by suitable measures (screening or relocating).
- When a display 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.
- 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
- 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.
