How
Your
Power
Inverter
Works
A
Rower
Inverter is
an
electronic product
thatisdesigned to convert
the
12
volts
of direct current
(DC)
usually from a battery into
120
voltsofalternafing
current
(AC).
This
conversion
enables
the
useofhousehold products
and
power
tools
away
from
the normal
AC
power
sources
(wall
outlets).
Suddenly
cans,
inicks,
boats
and
other
vehicles
can
use
TX’s
and
other
aprliances
like
microwave
ovens.
Lighting
and
tools
canbeusedinremote
locations,
The
conversion
process
first
changes
the
12
volts
DC
toamuch
higher
DC
voltage.
The
high
DC
voltage is then outputted inaforward
and
thenina
reverse
direction.
The
output
wavefoim
is
calledainod~f,ed
sine
wave
because
it
m.mic~
the
normal
AC
voltage
but
does
not
exactly
match.
Since
power
comes
from
the
productofcurrent
and
voltage,
evenasmall AC
appliance
that
requires
onlyafew
amperes of AC
current
will
drawalarge
DC
current
from your
battery.
Remember In
use
the
cables
that come
with
the
power
inverten
The
vast
majority
of
appliances
and
power
tools
have
no
problems with
the
modified
sine
wave
current.
However,
someDCchargers,afew
TV’s
and
VCR’s.
and some
compressoFdriven
products
require
a

for
proper

Installation
A)
Selecting
the
Battery
Power
Source:
The input power
source
you
are
conneding
to the
power
inverter
must have a
minimum
voltage
of
10.5
volts
toamaximum
of
14.5
volts DC. The power
source
most
likely
willbea combination a
vehicle’s
battery andalternator (when
tIle

W4RNING~
DO
NO~
INSTALL THE
POWER
INVERTER IN
A
POSITIVE GROUND
DC
SYSTEM.
The 300
Watts
that
your power
nveaer
is capable of
supplying
requires
30
amperesof
inputcurrent.
This means
that
in order to
avoid
draining
the
battery,
the
alternator
must
be
able to provide
at
least
150
amps.
All
passenger

and
small

B)
Placement
of
the
Power
Inverter:
Placement of the
inverterisimportant
for
maximizing
the
usefulness
and
life of
the
power
inverter.
For the best results, the
inverter
should be placed
on
a
sturdy,
flat
surface.
Note:
The
power
inverter
can be mounted in any position:
vertical,
horizontal,
uprightorinverted.
Consider
the
following
criteria
when
choosingapermanent
location:
1
Ventilation:
Make sure
thereisat least
one
inch
of clearance around
the power
inverter
for
maximum
airflow.
This’isespeciAlly
importa,it
when permanent mounting is being
considers.
Do not
place
objects
on
or over
the
power
inverter
during
use.
Air
must be able to
circulate.
The
built-in
cooling
fan
provides cooling,
but
must have
sufficient
open
space
to operate
properly,
In
the
event
that
internal

temperature exceeds
1504k
the
power
iawerter
will
automatically
shut
off.
2.
Dry:
Keep
Liquids,
water or any other type of wet substance
away
from
the
power
invert~.
When
choosing
a permanent
location,
stay
away from
spill
areas.
3.
Cool:
Best operating
emperaturc
rangeisbetween
45
and
85
0F Do
not place the power
inverter
in a
location
that could
be
affected
by
a
heating
duct or
any
other heat source
that
would
increase
the
normal
operating temperature of
the
power
inverter
-
4.
Safety:
Do
not
place
the
inverter
near flammable substances!!! Fumes
and
gases could
cause
and
explosion
or fire
that
would
result in
severe
damage
ard
possible
death.

Operation
I)
Plug
the
AC,
power cord of the item to
be
powered
by
the
power
inverter
into one
of
the
AC
outlets.
Make sure the power of
the
connected
product
is
turned
OFF.
Important:
If
two
products
are
to
be
powered,
make
sure
that
the
total
wattage
does not
exceed
the
total
capacity
of
the
power
inverter.
2)
Turn
ON
the
power
invertet.
3)Now turn
on
your
connected
product.
If
you
have
two
products
connected, make
sure,
that
you turn
them
on
sepatately.
This
will insure
thai
the
power
inverter
does
not
have
to
deliver the “peak”
