Cable gland installation for smaller vessels

This cable glands made of plastic is designed for those smaller

vessels that do not need to be classified.

(A) = Packing nut (bronze).

Ensure that you do not to

damage the transducer cable by

tightening the packing nut too

hard!

(B) = Rubber gasket

(D) = Rubber gasket

(E) = Stuffing tube

(F) = Backing nut (bronze)

(G) = Backing washer (plastic)

(H) = O-ring 42.5 x 3.0 N

(I) = O-ring 39.5 x 3.0 N

(J) = Cable to the echo sounder

(or a junction box)

Stuffing tube hole diameter : 36 mm ±1.5 mm.

Apply ample amount of sealant between the backing washer (H)

and the hull plate.

The cable gland kit contains all the listed parts, except the

sealant.

Note: The two O-rings must be clean, in good condition and free of cuts

or other defects which could affect their water-tight integrity.

Splicing

If you need to cut the transducer cable, you must splice it

correctly.

Note: DO NOT solder the wires together with only electrical tape for

insulation, as this will result in electrical noise and reduced

operational performance.

To splice the cable, use a metal junction box. The chassis of the

junction box must be grounded, but the cable shielding must

NOT be connected to the junction box ground.
