Raymarine ST60 Tridata - Manual (Page 35)

Chapter 3: Installation 23
Fitting transducer
The ST60 Tridata instrument is supplied, with appropriate through-hull
Speed and Depth transducers.
Each transducer is supplied with detailed instructions for installation and
maintenance. Before attempting to install a transducer, read these
instructions and the Site requirements for transducers described in this
Chapter.
Once you are satisfied you can meet all the installation requirements,
install the transducer in accordance with the accompanying installation
instructions.
Running transducer cable
Each transducer type has a 14 m (45 ft) cable fitted with spade terminals
for connection to the ST60 Tridata instrument. The manner in which you
run the cable will depend on the locations of the transducers and
instrument. The following guidelines are provided:
• 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.
• Do not route the cable through bilges.
• Wherever possible, route the cable away from fluorescent lights,
engines, radio transmitting equipment, as these may cause interfer-
ence.
• The transducer cables are fitted with spade connectors for direct con-
nection to the rear of the instrument. However, it may be necessary to
remove these to facilitate installation, e.g. if a cable has to be routed
through narrow apertures. Extra spade connectors are provided, to
replace any that are removed when running transducer cables. When
fitting spade connectors, prepare the cable as at (a) in the following
illustration, then fold back the wire strands and insert into the spade
connector as at (b). Ensure the wire strands do not extend beyond the
rear of the spade connector insulation, then crimp the connector to the
wire.
