Electrical & Communication Notes - Gemini 620pd Profiling Product Manual

Gemini Profiler Installation
If the fixing mechanism is designed such that the profiling heads can be withdrawn
from the water but left in place on the side of the vessel then consideration should be
given to the installation of a suitable cover to protect the head when not in use. The
head should be clamped securely around the main part of the body tube. Any metallic
clamps should be electrically insulated from the sonar body by either rubber or plastic
strips or mounting brackets of at least 3 mm thickness and extending at least 3 mm
beyond the clamp boundary to reduce any galvanic corrosion effect.
For ROV Installations
The sonar heads should be mounted in the correct orientation along the trim of the
vehicle and it should have an unrestricted view of the seabed.
