Heart Interface HF12-1200 - Page 4

In marine applications you
will
connect
to the existing
grounding
system.
The
ground
lugs in
the
output
sockets of the inverter
are connected
to
the
chassis
ground.
In
W models
the
green
wire
in the
junction
box
is
connected
ro
the
chassis
ground.
Thii
means
that when
you
plug
an appliance
with a standard
3 wire
grounded
plug
into
the
inverter,
the
ground
from
the
appliance
is
connected through
the inverter
to
ground.
The neutral
wire of
the
AC
output
is
attached
to
ground
in
the unit.
This
means
that when
you
connect the chassis to
ground,
you
are
also
connecting
the
neutral leg
to
ground.
\The
battery cables
from
the Heart are not
connected internally
to
the chassis. You
may
ground
either the
positiv€
or the
negative
battery.
Vt is very
important
for
safe
operation that
grounding
be carefully
done. Please
do not
operate
the
Heart without
the
protection
afforded
by
proper
grounding
of the
chassis.
AC
OUTPUT CONNBCTION:
HF12-1200U: This
model is equipped
with
a GFCI outlet
on the front
panel.
The
simplest
way
to use this
model
is
to
plug
your
appliances into
this outlet. You may
connect
this unit
to
your
existing
electrical
system
by
preparing
a 3 conductor
wire
with
a standard
household
plug
on one end
and connecting
the other
end
directly
to
a
circuit
breaker
panel,
an outlet box
or
a transfer
switch.
V-IF
12-
1200UW: These
models
do
not
have
an outlet
on the front,
but are
supplied with
a 3
foot
cable out the back of
the unit
which
terrninates in
an electrical
junction
box.
This
is
designed
to
facilitate hardwiring
into
your
electrical
system.
Use
appropriate
connectors
in
the
junction
box and
run
the
output
to
your
circuit breaker
panel,
outlet box or transfer
switch.
Vn
order
to
conform
to the National Electrical
Code, certain
branch circuits
must be
equipped with
a Ground
Fault
Circuit
Intemrpter
(GFCI)
such as Pass
& Seymour
Cat- No.
1591-RW.
Any
such branch
circuit
must
be
protected
a circuit
breaker consistent
with the
GFCI rating. In
the case of the HF12-1200U
the unit is equipped
with
the
GFCI. In
the case
of the HFI2-1200UW
a
GFCI
is
supplied separately.
TRANSFBR
SWITCHING:
Any
time two or more
sources of AC
electricity
are used i n
an
electrical
system
a transfer
switch must
be used to
isolate
the sources from
one another. The
transfer
switch is
double-
pole
double-throw,
and may
be an automatic relay
or a manual rotary
selector
switch.
IF
SHORE
POWER
OR A
GENERATOR
CAN
BE
USED, DO
NOTCONNECT
THE
INVERTER
TO YOUR
ELECTRICAL
SYSTEM
WITHOUT
A TRANSFER
SWITCH.
THIS
CREATES
A
BACKFEED,
DAMAGE
WILL R€SULT,
AND
YOUR
WARRANTY
WILL BE
VOID.
