DC
CONNECTION
PRECAUTIONS
IMPORTANT CABLE
INFORMATION
Use
cable
information
in
Appendix
A for
determining
gauge
of
cable.
Use
DC
Inverter
terminal
connections
on
cable
ends.
The
user
must
maintain
secure,
tight,
electrical
connections.
Use
correct
gauge
DC
cabling
to
supply
up
to
150
amps,
or
maximum
load.
Keep
cabling
short
to
avoid
voltage
drop
and
reduced
operating
time.
Inverters
are
supplied
with
a
grounding
terminal.
Connect
an
insulated
AWG
12
wire
to
this
terminal
and
connect
the
other
end
to
a
solid
electrical
ground.
This
is
an
important
safety
wire
that
ensures
proper
grounding.
DO
NOT CONNECT THIS
WIRE
DIRECTLY TO
THE
NEGATIVE
DC
INPUT TERMINAL OF
THE
INVERTER,
or
Battery.
At
full
1500
watt
load,
the
DC
input
requirements
are
up
to
150
amperes
at
12
volts
DC.
For
most
continuous-duty
applications,
multiple
battery
configuration
and
the
use
of
deep-cycle
batteries
is
a
requirement.
With
vehicles
using
multiple
batteries,
inverters
should
be
operated
from
one
of
the
vehicles
12
volt
batteries,
so
there's
always
one
battery
with
adequate
charge
to
start
an
engine.
LOCATION
CAUTIONS:
To
avoid
possible
dangerous
conditions,
the
inverters
must
be
located
where:
1. The
unit
is
kept
dry.
2. Air
temperature
is
between
30
degree
F
(-1
degree
C)
non-condensing,
and
105
degrees
F
(40
degrees
C).
3. At
least
three
inches
of
clearance
from
other
objects
is
maintained
for
cooling
airflow.
4. The
unit
is
not
exposed
to
direct
heat
or
sunlight
or
to
explosive
or
flammable
fumes.
5. The
unit
is
as
close
to
the
DC
power
source
as
possible.
