theory.
You
should
understand
parallel
and
series
hook-up
and
how
lo
qet
$ql*ggtygJ!1gg
and
current from
your
battery bank.
These
conceprs are
described
in
the BATTERY INTERCONNECTION
section.
CAUTION:
Do
not
arange
the
batteries in
a configuration
thar will
exceed
the
rated
input
voltage
of the
unit.
CAUTION:
Connecting
the inverter
to
the
batteries with
reverse polarity,
even for
an
instant,
will
cause damage
and void
the warranty.
Ensure
correct
polarily
before
connecting
the
DC
lines.
BATTERY
CONNECTIONS:
The inverter is
supplied
with two
battery
cables, each
36 inches
in
length.
Both
cables
ar-e.black,
but the
positive
(+)
cable has
a red
end.
If
you
need
to exrend
the
cables
beyond
36 inches,
you-must
extend
the
cables supplied
with 1/0
(00)
AWG
srranded
cable
of up to
!leet.AgTn,
do notexceed
10 feet
of battery
cable,
as
you
will
incur
excessive
voltage lbss.
You
must
be absolutely
certain
to maintain
correct
polarity
when
changing
to a longei
cable.
Always
install
a red
cable or
a
red
cable
end marker
on the positive
(l)
cable.
Fusing:
The tIF12-1200U
and
I{F12-1200UW
are
UL Listed
for
both marine
and
RV
appli-
cations. The
listing is
nullified
if installation
is
not accompanied
by appropriate
baiiery
fusing,
?s
per
33 CFR-183.46A
for marine
applications,
and
as
per
NEC-551-'51(e)
for
RV
applications.
_ _ _
Fo1.*arine
applications,
the fuse must
be within
six
feet
(
I .8
meters)
of the
battery.
For
RVapplications
the
fuse
must
be
readily
accessible
and
be
within
18 inches
(.45
meier)
of
the
battery.
. .The
average
*!ng
ojthgfgsg
must
not
exceed the value
appropriate
for
the
gauge
and
insulation
of the cables.
The
FIF12-1200U
and
HF12-1200UW
bome
with
strand-ed
iables
with
90
degree
C.
rated
insulation.
Therefore
you
must
use
a class
J
fuse
rated
at 200
amps.
_
Current may
flow
momentarily
when
the
battery
connection
is
made,
as
a
result

Wiringnotes:
Certain minimum
criteria
must
be met
in
wiring
your
inverter.
Always
use at least
16
AWG
suanded
wire for your
AC
output. In
marine
applications,
always
select
UL listed
boat
cable.
{or 91her_applications,
use
moisture
and fuef resistant
insulated
cable.
Always
use
sfanded
cable.
Stranded

than
