2.4.2.2 Connecting Cables to Water Column Electrodes
(16 Electrode System - See Page 2-WD.7)
The following assumes that the electrodes have been fitted to the water column.
1. Gain access to the electrodes mounted on the water column.
2. Undo both knurled nuts on the stud of the bottom electrode (referenced EL.1 on the
drawings) and remove both the nuts and washers.
3. Take one of the brown (BN) conductors in Cable 1 and fit the ring clamp of the
conductor over the stud, followed by a washer and a knurled nut. Tighten the nut to form
a good secure contact, ensuring the conductor run to the cableform clamping bar is free
from snags and sharp bends.
4. Repeat the operation for the remaining brown (BN) conductor of Cable 1.
5. Take the next electrode up, referenced EL.2 on the drawings, and repeat the operations
detailed in paragraph 2 above.
6. Take the brown (BN) conductors of Cable 2 and repeat the fitting instructions detailed in
paragraph 3 above.
7. Repeat the operations of paragraphs 2 and 3 for the remaining tabulated
conductor/electrode pairings on the next page and connect as detailed on page 2-WD.7.
8. Check that all conductor runs affecting Cables 1 and 2 on the water column are
satisfactory then clamp the cable securely to its clamping bar.
9. Refit any Electrode Protection Covers to the water column.
