as short as possible and twist them together with about 2 to 3
twists per foot. This minimizes radiated interference from the
cables.

8. Maintenance
Very little maintenance is required to keep your inverter operating properly. You should
clean the exterior of the unit periodically with a dry cloth to prevent accumulation of
dust and dirt. At the same time, tighten the screws on the DC input terminals.
9. Warranty
We warrant this product against defects in materials and workmanship for a period of 12
months from the date of purchase and will repair or replace any defective Go Power!
Inverter when directly returned, postage prepaid, to the manufacturer. This warranty will
be considered void if the unit has suffered any obvious physical damage or alteration
either internally or externally, and does not cover damage arising from improper use such
as plugging the unit into an unsuitable power sources, attempting to operate products
with excessive power consumption requirements, reverse polarity, or use in unsuitable
climates.
This is the only warranty and the company makes no other warranties, express or
implied, including warranties of merchantability and fitness for a particular purpose.
Repair or replacement are your sole remedies and shall not be liable for damages,
whether direct, incidental, special or consequential, even though caused by negligence
or other fault.

6.2 Overload
The fault LED will come on when the power inverter has shut itself down because
its output circuit has been short-circuited or drastically overloaded. Switch the ON/
OFF switch to OFF, correct the fault condition, and then switch the ON/OFF switch
back to ON.
Some induction motors used in refrigerators, freezers, pumps and other motor operated equipment require very high surge currents to start. The power inverter may not
be able to start some of these motors, even though their rated current draw is within
the power inverter.
If the motor refuses to start, observe the battery voltage indicator while trying to
start the motor. If the battery voltage indicator drops below 11 volts while the
inverter is attempting to start the motor, this may be why the motor will not start.
Make sure that the battery connections are good and that the battery is fully
charged. If the connections are good and the battery is charged, but the voltage still
drops below 11 volts, you may need to use a larger battery.
6.3 Input voltage
The power inverter will operate from input voltage ranging 10 V – 15 V. If the voltage
drops below 10.7 V, an audible low battery warning will sound and the fault LED will be
on. The power inverter will shut down if the input voltage drops below 10 V. This
protects your battery from being over discharged.
The power inverter will also shut down if the input voltage exceeds 15 V. This protects
the inverter against excessive input voltage. Although the power inverter incorporates
protection against over voltage, it may still be damaged if the input voltage is allowed to
exceed 20 V.

7. Troubleshooting
7.1 Common problems
a) Buzz in audio systems
Some inexpensive stereo systems will emit a buzzing noise from their loud speak
ers when operated from the power inverter. This is because the power supply in
the device does not adequately filter the modified sine wave produced by the
power inverter. The only solution is to use a sound system that incorporates a
higher quality power supply.
b) Television interference
Operation of the power inverter can interfere with television reception on some
channels. If this situation occurs, the following steps may help to alleviate the
problem.
• Do not operate high power loads with the power inverter
while watching television.
• Make sure that the antenna feeding your television provides
an adequate (“snow free”) signal and that you are using good
quality cable between the antenna and the television.
• Move the television as far away from the power inverter as
possible.
• Keep the cables between the battery and the power inverter
