IMPORTANT
POII\TS
Take
care to
observe
correct polarity
when
connecting
the
batteries
to
the Heart.
Reverse
polarity
connection,
even for
a moment,
will
damage
the
unit
and
void
the
warranty.
Do
not feed
AC from
the
utility
line
or
a
generator
into
the
oueur
of
the inverrer.
This
is
known
as backfeeding,
will
damage

SELBCTING
AN INSTALLATION
SITE:
There
are several
considerations
which go
into
selecting
a location
to mount your
inverter.
First is
saf9.ty,
but
cable length,
ventilation
and coolin!',
operating
temperature
and
environmental
conditions
must
also be considered.
The
F{F12-1200U
is
not ignition
protected,
and therefore
must
nor
be mounted
in
the
pre^sence
of
ignitable gases,
vapors,
dust
or liquids
or
in
any
other
"HAzardous
Location"
as
definedby
the
National
Electric
Code. Do not
mount
in
the engine
room
of
a
gasoline
powered
boat
or in an
airtigtrtcompartment
with
the
baneries.
If
in
doubr
about
a
pirticular
iocation,
consult
a
qualified
electrician
before installing
the product.
-
Although
it
is.designed
to
be
quite
rugged,
it
is
best
ro
prorecr
rhe inverter
from
the
elements.
Do
not allow
water
to splash
on the
unit
and avoid
tenlperature
extremes.
The
inverter
will
work best
in
an
ambient
air temperature
between
30 and 104
degrees
F.
(-
1
and
40
degrees
C.).
The
inverter
may
be mounted
horizontally
or vertically.
It
is
importanr
rhat
the
unit
be
secured
to
a flat surface
that
will
allow
air
to flow
under
rhe
unit.
You
should
ofro
piouiOi
for
some
air flow
around
the
unit. This
will
insure
adequate
cooling
when
operating
high
powered
loads.
It is
best
to
locate
the
unit
as close
as
practical
to the
batteries
so
as to keep
the
cables
short. It
is
better to
ru-nlonger
AC
wires
than
longer
DC
cables.
If
you
must
alter
the
cable
length,
use l/0
(00)
AWG
cable.
Do not
exceed
a-10
foot DC
cable iength,
due
to excessive
voitage
loss.
See
the
battery
connection
and
fusing
section for
more iiformation.
