Directive of the European Parliament and of the Council of 12 December 2006 laying down technical requirements for inland waterway vessels and repealing Council Directive 82/714/EEC (2006/87/EC) (repealed)

Article 9.08 Connection to shore or other external networks

1. Incoming supply lines from shore networks or other external networks to the installations of the onboard network shall have a permanent connection on board in the form of fixed terminals or fixed plug sockets. The cable connections shall not be subjected to any pulling load.

2. The hull shall be capable of being earthed effectively when the connection voltage exceeds 50 V. The earthing connection shall be specially marked.

3. The switching devices for the connection shall be arranged such as to prevent the concurrent operation of the onboard network generators and the shore network or another external network. A brief period of concurrent operation shall be permitted when changing from one system to another without a break in voltage.

4. The connection shall be protected against short circuiting and overload.

5. The main switchboard shall indicate whether the connection is live.

6. Indicator devices shall be installed to enable comparison of polarity in the case of direct current and phase sequence in the case of three-phase alternating current, between the connection and the onboard network.

7. A panel adjacent to the connection shall indicate:

(a) the measures required to establish the connection;

(b) the type of current and the nominal voltage and, for alternating current, the frequency.
