NOTES:
After the cables have been routed,
fill the hole with a
good marine
sealing
compound. Offset the bracket to cover the hole. Route the power
cable
through
the slot and break out one of the other slots in the bracket for the
transducer cable.

POWER CONNECTIONS
The tJltraNavGPS works from a twelve-volt
battery system only. For the
best
results, attach the
power
cable
directlyto
the
battery.
You can attach
the
power
cable to an
accessory or
power
buss,
however
you may
have
problems
with electrical interference. Therefore, it's
safertogo
ahead and
attach the
power
cable directly
to the battery. If the cable is not long
enough, splice
#18 gauge
wire onto it.Attach the in-line fuse
holderto the
red lead as close to
the power
source as possible. For
example, if
you
have
to extend the
power
cable
to the
battery
or
power
buss,
attach one
end of the fuse holder
directly
to the battery
or power
buss. This will
protect
both
the unit and the
power
cable in the event of a short.
The
powercable
hasthree
wires, red, white, and black. Red is the
positive
lead, black is negative or
ground. The
white
wire is used for the NMEA
interface. To usethis
feature, attach a
shielded,
twisted
paircable
fromthe
autopilot orother marine
equipment's NMEA interface tothe white wire on
the UltraNavGPS's
powercable. Solderthetwisted
pairs ground
wire and
shield wire to the black wire on the UltraNavGPS's power
cable. Do not
connect the shield wire to the autopilot. See your autopilot's manual for
more
instructions. If
you're not
going
to use this
feature, cut and tape
the
white wire to prevent
shorts.
The UltraNavGPS has reverse
polarity protection. No
damage
will occur
to the unit if the
power
wires are hooked up
backwards. However, it won't
work until the
wiring is connected properly.
