POWER SOURCES
2.3.1 All navigation equipment installed on the ship should be provided with power from the main and emergency sources of electrical energy.
2.3.2 The switchboard of navigation equipment must be powered from the main switchboard and emergency switchboard by two independent feeders (see also part XI "Electrical equipment" of the rules for the classification and construction of sea-going vessels).
2.3.3. The power of shipborne navigation equipment should be provided in accordance with the requirements of Table. 2.3.3.
On board it is recommended to provide an uninterruptible power supply device that ensures the operation of navigation equipment and the safety of navigation information in case of failure of the main and emergency sources of electric power, and also during the period of time required for switching from the main source of electrical energy to power from an emergency source or back. At the same time, light and sound signaling about switching to power supply using the uninterruptible power supply should be provided in the place from which the ship is usually operated. The alarm must be non-disconnected and must automatically return to its original state after the restoration of the electric power supply from the ship's network.
2.3.4 All navigational instruments and devices (with the exception of a gyro compass and course control system or a ship trajectory) designed to supply electric power must be powered by separate feeders from one common shield of navigation equipment.
The gyro compass must be powered in accordance with 3.7.2.3 (3.7.2.3 The gyrocompass must be powered from the main switchboard and emergency switchboard via two independent feeders).
The course management system and the ship's path control system shall be powered in accordance with 5.5.1 2 of Section XI Electrical Equipment of the Rules for the Classification and Construction of Sea Vessels.
2.3.5. If certain types of navigation equipment are to be powered by various primary kinds of current or different primary voltages, it is permissible, on an exceptional basis, to supply such equipment from other switchboards, with their mandatory location near the main shield of navigation equipment.
2.3.6 When feeding certain types of equipment from additional switchboards, these boards must be powered from the respective sources by separate feeders.
2.3.7 Switches and fuses or installation circuit breakers on the outgoing lines for each type of navigation equipment shall be provided on the switchboard (boards) of navigation equipment.
Connection to the navigation equipment panel of consumers that are not related to navigation equipment is not allowed.
2.3.8 Any battery, the use of which is permitted for the emergency power supply of several consumers, must be of sufficient capacity to provide the required table. 2.3.3 duration of continuous operation of all connected consumers at the same time without additional recharging.
