Underwater Cable connection to the Gauge
The Cygnus MINI ROV Gauge is provided with a fully-waterproof
external (“Impulse”) cable connection. To maintain the integrity of
the electrical operation and watertight-seal it is essential that
these precautions are observed:
Cable connection should only ever be made in
dry, ambient
conditions
at the surface.
Connections must never be made, or broken, underwater
Both the male underwater cable Connector and the Blanking-
plug should have Silicone grease smeared on the pins before
inserting into the female socket-connector on the Gauge
The male plug-connector should be pushed fully into the female
socket-connector, and then the
rubber retaining-loop
should be
pushed into the groove on the male-connector to complete the
fully-waterproof connection
