Panel. To prevent this problem we recommend installing the unit in a
vertical position (±30 degrees) to improve the airflow through the unit.
4. 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 a non-optimal way of mounting.
5. Exposure to extreme direct sunlight can cause a considerable increase in
the temperature of the unit and might under certain circumstances lead to
over-heating. This point should already be taken into consideration when
the bridge equipment is being planned (sun shades, distance from the
windows, ventilation, etc.)
6. Space necessary for ventilation, for cable inlets, for the operating
procedures and for maintenance, must be provided.
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 C-NaviGator III 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. Cooling of the C-NaviGator III 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 the C-NaviGator III 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 center of the magnetic system of the compass to the
nearest point on the C-NaviGator III. The compass safe distance of the C-
