Installation
Installation and mounting of computers
1. Most of our units are intended for various methods of installation or mounting
(rack mounting, panel mounting, bracket mounting, ceiling/wall mounting)
2. Adequate ventilation is a necessary prerequisite for the life of the unit. The air inlet and outlet
openings must definitely be kept clear; coverings which restrict ventilation are not permissible.
3. 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.)
4. Space necessary for ventilation, for cable inlets, for the operating procedures and for
maintenance, must be provided.
5. To further improve the cooling of the unit we recommend installing Cooling Fans underneath
blowing upwards into the unit 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).
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 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.
- 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.
Cables
Use only high quality shielded signal cables. For RGB/DVI cables use only cables with separate
coax for Red, Green and Blue. We can supply a varity of high quality RGB/DVI, RS232,
PARALLEL, LAN and USB cables intended for this use.
