Each cable must be fitted with a protective hose. The protective hose starts inside the transducer. Protection must be used along the entire length of the cables, and all the way up to where the cables penetrate the hull.
NoteThe protective is hose is fitted to the transducer cables during the production. For this reason, the length of the hose must be specified when you order the transducer.
The transducer cables must be properly fastened at the bottom of the drop keel, and fully supported while lowering and hoisting the drop
keel. Proper arrangements must be made to handle the cable slack when the drop keel is in its upper position. Depending on the drop keel design, the cable slack can be kept on the outside of the drop keel, or inside it.
The cables must be permitted to move freely when the drop keel is lowered and hoisted. It is important to avoid sharp edges or protruding elements, as these may cause damage to the cables. Observe the limitations for the cable minimum bending radius. Any damage to a cable may cause water ingression. Water follows the cable cores into the transducer, and causes damage that can not be repaired.
NoteWherever the cables are unprotected outside the drop keel, use a flexible conduit for protection.
Observe the cable specifications and limitations.
