2.4.2ELECTRICAL INSTALLATION

This section deals with the interconnection between the electrodes and the electronic enclosure, the connection of the ac mains power supply to the electronic enclosure and the analogue output connections from the electronic enclosure.

2.4.2.1Electrode Connections Hydrastep Electrode Cables

Special electrode cable assemblies of length 3, 10, 18 or 30 metres are provided with the system for connecting the Hydrastep 2468 Electronic Enclosure to the Water Column Electrodes. The cable looms are 18-core multi-strand conductors.

The conductors are colour coded for ease of installation and have pure nickel ring clamps fitted at one end for connection to the electrodes. A set of wire crimps is provided for use on the Enclosure connections.

The black conductors in each cable are used for the EARTH terminations, leaving eight pairs of coloured conductors for connection to the electrodes. At least one cable assembly is required and certain conductor pairs in the cables will be redundant. The exceptions are the 8, 16 and 32 electrode systems where all the conductors in the cables are fully used.
