Chapter 4 Installation
4.1 Installation consideration
General
Qualified service technicians should perform the installation of CVS-833/833C 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 and transducer
(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 are identical to what specified in the Device
Composition List in Chapter 2. 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 Positioning 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 cable should be 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 no possible, either cable set should be screened with
metal conduit or another form of shielding.
(2) The display unit should be grounded to the hull as short as possible using a thick braided harness
lead connected to the 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 the conducted
RF noise from other equipment on board.
