Mounting
Atest load that can be plugged into the AC receptacle on
the inverter for short term testing at a low power level.
The following cables are recommended for testing low
power level test loads only.
Test Load Minimum
Power Cable Size
100W # 16 AWG copper
250W # 12 AWG copper
500W # 8 AWGcopper
To check your inverter’s performancebefore installation:
1.Turn the inverter off (see page 14
for details). If the power source is
a DC powersupply, switchit off
as well.
2.Connect cables to powerinput
terminals(see page 8 fordetails).
3.Connect cables to powersource
(see page 8 fordetails).
4.Check to make sure all
connectionsare secure.
5.Turn the inverter on. If the
power source is a DC power
supply, switch it on first.
6. Plug inthe test load.
The inverter shouldsupply power
to the load. Ifthe inverter is not
working properly, refer to the
troubleshooting guide on page 18
or power andprotection indicators
section on page 16.
Installation Requirements
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 one inch (three cm) of clearance 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 compartment that contains
flammable liquids such as gasoline.
E. Close to Battery
Install unit as close to battery 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).
CAUTION To avoid fire, do not cover or obstruct
ventilation openings. Do not install inverter in a zero-
clearance compartment. Overheating may result.
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.
