Chapter 2: Installing the Scanner 25
CAUTION:
If any wires are damaged when the clamp is fitted, the scanner
unit will not function correctly.
• The ferrite clamp is supplied open. If the clamp has been
closed, insert a small, flat-blade screwdriver into the slots at
the end of the clamp opposite the hinge and twist gently.
• Position one-half of the clamp around the eight cores of the
inter-unit cable between the 8-way plug (4) and the cable
clamp, as close to the 8-way plug as possible. (It may be nec-
essary to fit the clamp over the cable tie closest to the 8-way
plug – this will not affect the ferrite clamp’s function).
Note: on the 24" scanner, the clamp must be contained inside the in-
ner cover.
• With the clamp positioned correctly, close the clamp ensuring
none of the cores are trapped by the hinge, latch or the ferrite
itself.
9. Connect the 8-way plug (4) to the connector (5). The correct fit-
ting is with the small arrow marked on the body of the plug facing
upwards and to the left hand side. The grey wire will then be at the
left hand side and the white wire will be at the right hand side.
10. Connect the red and black power cores (6).
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 (7) are operated using a screwdriver (8), as
shown in the inset diagram on the previous page.
CAUTION:
Do not earth the cable screen to the scanner. The radar system is
earthed via the display unit.
11. Secure the nut (1) on the watertight gland, making sure that it
grips the cable’s outer sheath.
12. Secure the cable with the cable clamp (9), using the two screws
(10) provided. The clamp can be installed either way up, depend-
