Chapter 4 Installation
4.1 Installation consideration
General
Qualified service technicians should perform the installation of CVS-842/852/843 series that
comprises the following operations.
(1) Unpacking each component of the system.
(2) Inspection of the exterior of each component unit and accessory.
(3) Checking the ship’s mains voltage and current capacity.
(4) Determining the installation site
(5) Installing the Display unit
(6) Planning the cable routing and connections
(7) Adjustment and setups
4.2 Unpacking each component of the system
Unpack your package and check if all of the items stated in the packing list are contained in the
package. If not, report this to an insurance agent for tracing missing goods or refund.
4.3 Inspection of each component unit and accessories
Carefully check the exterior of each component unit for dents, damage, etc. Also check the inside of
component units for electrical and mechanical damages.
4.4 Siting the units
To achieve best operational performance, the following factors must be considered.
(1) The display unit should be positioned in the location where the external
situation can be viewed.
(2) Locate the display so that it provides easy viewing from all likely operator’s positions.
(3) Select a position safe and free from dampness, water spray, rain and direct sunlight.
(4) Provide enough space for servicing. Consider access to the rear panel for connecting various
cables.
(5) Position the display unit as possible away from other radio equipment.
4.5 Cable routing and connections
(1) The transducer cables should be securely fastened to the TX/RX chassis using strain relief cable
clamps and run separately away from other cables such as, radio antenna feeders, power cables,
etc. Under no circumstances should it be in parallel arrangement with other cables. These
precautions are essential to avoid radio interference to/from other equipment installed on the
ship. If this arrangement is not possible, either cable set should be screened with a metal conduit
or another form of shielding.
(2) The display unit should be grounded to the hull as short as possible. We recommend using a
wide and heavy copper braid or plate to be connected to a grounding stud at the rear of the
display unit.
(3)
The power supply cable should be connected directly to the ship’s battery to avoid RF noise
conducted from other equipment on board.
