13.3.2.4. Grounding the Display Cabinet
Figure 13-8 Ground Terminal
・
The display cabinet, which is electrostatically coated
inside, can be grounded to the ship’s earth ground
without grounding the negative line of the power source.
・
In installations where it is required, or desirable, to
ground the cabinet for safety reasons or EMC

compliance, connect from the wing – nut–fitted ground
terminal on the rear panel to the ship's nearest earth
ground using a thick wire.
・
The ground wire should be as short as possible to reduce the chance of picking up
interference from other electronics.

:
EMC = electromagnetic compatibility
13.3.3. Connections to Transducer
・
The transducer is supplied with its integral cable. A three–hole female–type plug is
separately supplied for terminating the cable for connection to the equipment cabinet.
・
With the aid of the illustration below, disassemble the plug, taking care not to lose the
small screws.
< WARNING >
DO NOT TURN THE EQUIPMENT ON WITH THE TRANSDUCER PLACED IN THE
AIR, OR DAMAGE TO THE TRANSDUCER CRYSTAL WILL RESULT.
・
Cable Extensions:
- In installations where the existing integral cable must be extended, be sure to use the
same type of cable supplied by the manufacturer.
- Use of additional cable not approved by the manufacturer will seriously degrade the
depth detection performance.
- All joints must be made by soldering and properly insulated. “ Twist–and–tape ”
connections must be avoided.
- Coaxial cables are electrically unbalanced and cannot be used .
