Chapter 3: Installation 23
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 interference.
• The transducer cables are 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 a cable has to be routed through narrow aper-
tures. 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 con-
nector to the wire.
Observing the above guidelines, run the transducer cables to the ST60 Tridata
instrument.
