3.1.2 Electronics Units
Dimensions, weights, spaces required for service and maintenance and special installation instructions
are stated in the outline drawings and installation drawings of the corresponding unit. In general, the
following points also apply:
- The useful life of the components of all Electronics Units (Pulse Generators, Transceivers etc.)
generally decreases with increasing
ambient temperature ; it is therefore advisable to install such
units in air-conditioned rooms. If there are no such facilities - e.g. deckhouse or space near or below
the water line - these rooms must at least be dry, adequately ventilated and kept at a suitable
temperature in order to prevent the formation of condensation inside these units.
- With most Electronics Units, cooling takes place via the surface of the casing.
The cooling must not be impaired by partial covering of the unit as a result of insulation (if any) of
the room (the wall on which the casing is mounted), or by installation of the unit in a confined
cabinet.
Furthermore, the distance from the ceiling and the floor or from a unit situated underneath must be
at least 300 mm.
- For service purposes, a power socket (AC 220/230 V) and adequate lighting are necessary in the
vicinity of each Electronics Unit.
- 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.
