Chapter 3: Installation

• If the cable has to be fed through the deck, always use a proprietary

deck gland.

• Where cables are fed through holes, always use grommets to

prevent chafing.

• Secure long cable runs so they do not present a hazard.

• If the transducer is mounted on a masthead or other structure likely

to be removed for maintenance or storage purposes (e.g. a mast),

always incorporate a junction box into the cable run as close as

possible to the cable entry point into the vessel, to facilitate

disconnection when required.

• The transducer cable is fitted with spade connectors for direct

connection to the rear of the instrument. However, it may be

necessary to remove these to facilitate installation, e.g. if you want

incorporate a junction box in the cable run or if the cable has to be

routed through narrow apertures. Extra spade connectors are

provided, to replace any that are removed when running the cable.

In order to ensure a secure connection when fitting spade

connectors, fold back the wire strands as shown in the following

illustration, before inserting the wire in the spade connector. Ensure

the wire strands do not extend beyond the rear of the spade

connector insulation.

From masthead

If the transducer is fitted on a masthead:

1. Remove the spade connectors from the free end of the cable, then

feed the free end of the cable down inside the mast.

• If the mast is a through-deck mast, feed the cable out through a

suitable below-decks aperture.

• If the mast is deck stepped, feed the cable through the deck,

using a proprietary deck gland.

2. Fit the junction box inside the vessel, close to the cable entry point.

3. Run the cable to the junction box, then allowing sufficient cable to

connect inside the junction box, cut the cable and connect each

wire at the free end of the cable from the transducer, to a separate

connector inside the junction box.
