Mounting
Mount the inverter on a flat surface placing the
mounting bracket on the bottom. Mounting
hardware should be corrosion resistant and at
least #10 or larger.The inverter can be mounted
horizontally or vertically.
Cables (included)
Power wire and wiring is very important to the
performance of the inverter.Because the inverter
has a low voltage,high current input,low resis-
tance wiring is essential between the battery and
inverter.This is so it can deliver the maximum
amount of energy to the load.
Use only copper wire.Aluminum wire has about
1/3 more resistance than copper wire of the
same size plus it is difficult to make good,low-
resistance connections to aluminum wire.
We recommend #4 copper cable (90° C insulation
rating) as the minimum size for connections
between the battery and inverter.
Keep the cable length as short as possible,no
more than 4 ft.(1.5 meters).This will keep the
voltage drop to a minimum.
Mounting
CAUTION: The inverter must
only be connected to batteries
with a nominal output voltage
of 12 volts.It will not work with
a 6 volt battery,and will be
damaged if it is connected to
a 16 volt battery.
WARNING: If you are making a
permanent AC connection to
the inverter,make sure that the
AC wiring steps are performed
before any DC wiring is done.
(DC hook-up energizes internal
components,regardless of the
position of the ON/OFF switch).
Working on AC connections in
such a circumstance may result
in an electric shock.
WARNING: 115 Volt AC power is
potentially lethal.Do not work
on AC wiring when it is connect-
ed to the inverter (even if it is
switched off) unless the DC
power source is physically dis-
connected from the inverter.
Also,do not work on AC wiring
if it is connected to another AC
power source such as a genera-
tor or the utility line.

Installation
The inverter must be installed in an area that
meets all of the following requirements:
A. Dry- Do not place in an area where water can
drip or splash on the inverter.
B. Cool- Ambient air temperature should be
between 30° F and 105° F (0° C and 40° C).
The cooler the better.
C. Ventilate- Allow at least 1 inch (3cm) of clear-
ance around the inverter for proper airflow.
Make sure that ventilation openings on the
ends of the unit are not obstructed.
D. Safe- Do not install the inverter in the same
compartment as a battery or in any compart-
ment that contains flammable liquids such
as gasoline.
E. Close to battery- Install unit as close to bat-
tery as possible (without being in the same
compartment) to minimize the length of
cable required to connect the inverter to the
battery.It is better and cheaper to run longer
AC wires than longer DC wires (cables).
Installation
CAUTION: To avoid fire,do not
cover or obstruct ventilation
openings.Do not install invert-
er in a zero-clearance com-
partment.Overheating may
result.
WARNING: This unit contains
components which can pro-
duce arcs or sparks.To prevent
fire or explosion,do not install
in compartments containing a
battery or flammable mater-
ials,or in a location which
requires ignition protected
equipment.
