Chapter 2: Installing the Scanner 25
9. Connect the red “+”and black “-” power cores (7).
If you have a 10 m or light 15 m inter-unit cable, there is one pair
of cores. Connect the red cable lead to one of the terminal sockets
marked “+”, and the black cable lead to one of the sockets marked
“-”.
If you have a heavy 15 m inter-unit cable, there are two pairs of
cores. Connect the red cable leads to the terminal sockets marked
“+”, and the black cable leads to the terminal sockets marked “-”,
with one lead in each socket.
The terminal clamps (8) are operated using a screwdriver (9), as
shown in the inset diagram on the previous page.
10. Secure the nut (1) on the watertight gland (2), making sure that it
grips the cable’s outer sheath.
11. Secure the cable with the top clamp (11), using the two screws
(12) provided. Ensure that the clamp goes around the exposed
wire braid, and that the wire braid makes contact with the earthing
clamp. Tighten the screws until the top clamp deforms just
enough to contact the lower earthing clamp (see inset).
CAUTION:
It is essential that the drain tube is fitted and that the nut on the
watertight gland is adequately tightened. If this is not done, water
could become trapped in the scanner and cause irreparable
damage.
12. Tighten the securing nut (1) again to ensure a waterproof seal.
13. If you have a 4D scanner, replace the inner cover over the connec-
tors.
14. Untie the cord from the scanner cover, and coil it up in the
base of the scanner unit so that it cannot foul the rotating
antenna.
15. Replace the scanner cover, aligning the mark on the cover with
the mark on the scanner base above the cable gland, and tighten
the 4 or 7 captive screws. Do not over-tighten these screws.
