28 Capricorn II Plus User Manual
a. drill a 3/8" hole though the wall (1/2" if combined with the temperature sensor
cable);
b. insert a pair of small plastic wall bushings (available as an option; see Section 4)
on either side of the wall (or, insert a wall feed-through tube, also optionally avail-
able); and
c. thread the cable through the bushings or tube.
Make sure that the exposed portion of the sensor cable that is beyond the mast will
not be blown about by the wind. Use insulated eye bolt standoffs or other fasteners
if necessary. (See Section 4.)
Note: If the standard 50 ft. cable provided with the wind sensor assembly is not
long enough, it may be extended by splicing on an appropriate length of 22 gauge,
stranded, seven conductor cable with the same color code. When cutting and
splicing, insure good contacts, proper color coding of the terminal leads, and a good
seal. (A good solder splice and water proof insulation are essential; merely twisting
the respective wires together is not adequate.) Additional cable (Cat. No. 81540)
and a water tight splice kit (Cat. No. 81580) are available from the factory. The
maximum length of the cable (original cable plus spliced section) should not exceed
1000 ft. (305 m).
Using a Phillips screwdriver, attach the seven colored wires from the end of the wind
sensor cable to the matching terminal post screws protruding from the back panel of
the console below the label, “Wind Sensor Cable.” The screws are labeled to match
the corresponding wire colors. See Figure 2.
F. LIGHTNING EARTH GROUND
Customers who desire to provide a lightning earth ground for the Capricorn II Plus
console are encouraged to do so.
Drive a 5/8" x 8 foot solid copper ground into the earth. Use a suitable ground rod
wire clamp and connect a #12 AWG. solid copper wire from the ground rod to the
chassis ground terminal on the Capricorn II Plus rear panel. A solderless crimp
terminal is provided for this purpose on the back panel of the console.
