Lowrance electronic X-3 a 3

POWER

CONNECTIONS

Twelve volt DC power should be supplied by

the boat's electrical system.

The

power cable may be

attached to an accessory

or power

buss, but if

you have problems

with electrical interference

(random

dots or lines that

show whenever the boat's engine

or other accessory

on),

the cable

should be attached directly to the battery.

The

power cable has two

wires, red for the

positive

lead and black is

ground or negative.

An in-line fuse holder

containing

a 3

amp fuse is

supplied

with the X-3. This should be attached

to the red wire on the

power cable with the

crimp connector. The

other end of the fuse holder

should be attached

to the

battery

or accessory

buss.

the cable is not

long enough, splice ordinary

#18 lamp cord to reach.

Just be certain that

the fuse holder is as close to the power

source (battery

or accessory

buss)

as possible.

This will protect the

power cable and unit

in the event

of a short The X-3 is protected from accidental

polarity reversals and will

not be harmed if the

wires are reversed. (However, the unit

will not work

until the

proper polarity is applied.)

Electrical noise picked up

by the power cable can be minimized

by rout-

ing it away

from other

possible sources of electrical interference. One of

the largest

noise generators is the

engine's wiring harness that runs from

the

engine

to the boat's instrument

panel. This harness

usually

contains a

wire for the tachometer which radiates RF

(radio frequency)

energy. For

the

best

results,

keep the

power and transducer

cables away from the

engine

wiring. Bilge pumps

are also noisy, so

try

to keep

the X-3's cables

away from them,

too.

VHF radio antenna's coax cable radiate RF energy

higher power levels

than even the

engines wiring hamess. It is

very important

to keep

the

X-3's

power

and transducer cables as far

away as

possible

from the VHF

radio's antenna cable.
