2. Construct a platform (steel or aluminum)
referring to the outline drawing and the
mounting template. Fasten the platform to
the mounting location. The holes in the
platform must be parallel with the fore and
aft line.
3. Put the radar sensor on the platform with
the bow mark ( U ) on sensor aligned with
the bow.
4. Use hex bolts*, flat washers and spring
washers (removed at step 1) to fasten the
radar sensor to the platform. The torque
for the bolts must be 19.6 to 24.5 N•m.
*See the figure below to determine bolt
length to use.
5. Connect the supplied power cable to the
sensor. Observe the guidelines for laying
the power cable shown on this page.
6. Connect the power cable to the power
source.
Guidelines for laying the power cable
• The connectors must not strike any part of
the vessel by wind, etc.
• The load applied to the connectors must
not be more than its own weight.
• If the cable is passed through a mast on a
sailboat, be sure the cable does not touch
ropes (sheet, halyard, etc.).
• Do not fasten the cable to the hull.
• The cable must be fixed so no tension is ap-
plied to the connectors. To prevent tension,
create a loop in the cable close to the sen-
sor and tie the loop with cable ties, as in the
figure below.
• Wrap the junction of the connectors with
self vulcanizing tape for waterproofing.
• Fasten the cable to the mast, etc. at the
neck of each connector with a cable tie.
