Quick Evaluation Before Installation
•
This section provides you with basic information about
the inverter and how to check its performance before
installation.
Be Sure to Have on Hand:
A 12 volt DC power source (such as a vehicle battery).
The power source must provide
between 11 and 15 volts DC and
be able to supply enough current to
run the test load. As a rough guide,
divide the wattage of the test load by
10 to get the current (in amperes)
the power source must deliver.
The provided 2 ft. cigarette lighter cable.
Only use the cables provided with
your inverter. The cigarette lighter
cable is suitable for operating the
inverter at loads up to 150 watts.
Connect by securely inserting the
plug into the cigarette lighter socket.
CAUTION Do not use the cigarette lighter cable
for loads higher than 150 watts. When connecting
loads larger than 150 watts, please connect the
inverter directly to the battery.
A test load that can be plugged into the AC receptacle on
the inverter for short term testing at a low power level.
To Check Your Inverter’s Performance Before Installation:
1. Turn the inverter Off (see page 11
for details). If the power source is
a DC power supply, switch it Off
as well.
2. Connect cables to Power Input
Terminals (see page 8 for details).
3. Connect cable to power source
(see page 8 for details).
4. Check to make sure all
connections are secure.
5. Turn the inverter On. If the power
source is a DC power supply,
switch it On first.
6. Plug in the test load.
The inverter should supply power
to the load. If the inverter is not
working properly, refer to the
Troubleshooting Guide on page 14
or Power and Protection Indicators
section on page 12.
