Cable System
Power Source – Lead-acid automotive batteries that supply between 12 and 28 V DC are used for the
power source. For bores shorter than 1000 ft (305 m), one 12-V battery will suffice. If the bore length
increases beyond 1000 ft (305 m) or advance rates decrease, additional batteries may be added in series
(see diagram).
Connect batteries in the order shown by the numbers in circles: 1 , 2 , 3 , 4

Non-DCI Supplies Required for
Operating the Cable System
Items such as compression fittings, 10-gauge copper wire, heat shrink, butt splices, and collector ring
assemblies are not available from DCI. Drill manufacturers or tooling manufacturers will have information
on collector ring (slip-ring) assemblies, mud swivels, and compression fittings. Electrical supply houses
will carry the rest of the equipment needed to connect the wires as drill rods are added to the drill string.
A new option available from DCI is a product called the CableLink
®
connection system, which eliminates
the need for butt splices and heat shrinks. The CableLink system is permanently installed into the drill
pipe, and the wire connection occurs automatically when the pipe ends are threaded together. For more
information, contact DCI.
NOTE: A multimeter should be available for power testing/troubleshooting. For detailed
instructions on troubleshooting the Eclipse cable system, please contact DCI.
