3.3 Connector Maintenance Guidelines
Mating surfaces should be lubricated with 3M Silicone Spray or equivalent, DO NOT GREASE. Connectors must
be lubricated on a regular basis.
Clean plugs and receptacles with soap and fresh water. If using alcohol or IPA to clean out the connector take
care that it does not come into contact with any other part of the sonar.
When attaching a connector make sure that both connector and socket are completely dry. Any water trapped
in the connection could result in an electrical short and permanent damage to the sonar
If the Gemini has two ports then any unused bulkhead connector must have a blanking cap fitted prior to
immersing in water. Failure to do this will permanently damage the sonar.
3.4 Ground Fault Monitoring
The power supply within the Gemini includes an electrically isolated DC-DC converter front-end. There is a small
capacitive connection between the isolated ground and the sonar chassis which should not noticeably affect
any impressed current ground fault indicator (GFI) equipment.
3.5 Test Cables and Accessories
Deck test cables are available to aid with the setup and configuration of the sonar while on or off the vehicle.
Tritech recommend the use of the deck test cables (below) as the first step in any diagnostic or fault finding
activities.
WARNING
The Gemini PSU that is supplied with the Gemini system is intended for INDOOR
USE ONLY and should not be placed in a position where it could get wet.
3.6 Subsea Cable Whips & Test Leads
