2468CB & 2468CD Dual Power Supply Version Hydrastep 2468CB and 2468CD Manual

2.4.2 ELECTRICAL 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.
2.4.2.1 Electrode 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.
