ACU and the Terminal Mounting Strip. Refer to the vendor supplied manuals for installation of the other
below decks equipments.
Prepare other locations throughout ship for any other equipment which is not co-located with the ACU.
3.3.5.
Install appropriate cables from Below Decks Equipment to the ADE Location(s).
Installing The System Cables
The cables must be routed from the above-decks equipment group through the deck and through various ship
spaces to the vicinity of the below-decks equipment group. When pulling the cables in place, avoid the use of
excessive force. Exercise caution during the cable installation to assure that the cables are not severely bent
(proper bend radius), kinked or twisted and that connectors are not damaged.
Assure that the cables have been run through watertight fittings and/or will not permit water entry into the
ship when the installation is completed. After cables have been routed and adjusted for correct cable length
at each end, seal the deck penetration glands and tie the cables securely in place.
3.4. Assembling the ADE
The assembly procedure described below begins by sub-assembling sections of the baseframe, radome and pedestal.
Then these are assembled to form the ADE.
3.4.1.
Read this entire assembly procedure before beginning.
Preparing for Assembly of the ADE
Refer to the System Block diagram, General Assembly, Baseframe Assembly, Radome Assembly and Radome
Installation Arrangement drawings for your system.
Select a secure assembly site that provides enough area to work with the large radome panels while sub-
assembling the baseframe, sections of the radome, Antenna Pedestal and Reflector & Feed. The area should
be a clean, flat location, free of rocks & debris (ie concrete). The site should also provide protection from
wind, rain and other adverse weather. A hoist, or small crane, is needed to assemble these sub-assemblies to
form the final ADE Assembly.
As an example, you might sub-assemble everything on the pier where the ship will tie up, then use the crane
to put the sub-assemblies together and lift the whole ADE up to the mounting location on the ship.
You can change order of these steps, however, in the end the objective is to have a well sealed
radome with flanges that are clean of excess caulking. In addition it is important that the ADE is
structurally sound for severe weather conditions.
3.4.2.
Refer to the Base Frame Assembly drawing for your system and the procedure below.
Sub-assemble the Base Frame Assembly
NOTE: Unless otherwise indicated, all nuts and bolts should be assembled
with Loctite 2760 or its equivalent.
1. Assemble the two halves of
the base frame using the
splice plates and hardware
provided. Apply Loctite and
tighten hardware to specified
torque.
