exceeds 16.5 +/- 1.0 V DC.
4. Under Voltage Protection. The inverter will automatically turn itself off when the input is
less than 10.0 +- 0.5 V DC.
5. Overload Protection. The inverter will automatically turn itself off when the continuous
draw of the equipment being operated exceeds 650 W or the surge draw of the equipment
exceeds 1200 W.
6. Thermal Protection. The LED Status Panel will illuminate RED and the inverter will
automatically turn itself off when the circuit temperature exceeds 150°F.
7. Overheating Protection. The inverter is equipped with a cooling fan, which is designed to
run continuously while the inverter is operating. Automatic shut down of the unit caused by high
circuit temperatures will occur when the cooling fan is unable to maintain a temperature safe for
operation.
In the event of automatic shut down or a continuous audible alarm, turn the inverter power switch to
the OFF (O) position until the source of the problem has been determined and resolved.
Television and Audio Suggestions
Although all Pure Sine Wave Inverters are shielded and filtered to minimize signal interference, some
interference with your television picture may be unavoidable, especially with weak signals. However, here are
some suggestions that may improve reception:
1. Make sure the television antenna produces a clear signal under normal operation conditions
(plugged into a standard 110-volt AC outlet). Also, ensure that the antenna cable is
properly shielded and/or of good quality.
2. Change the position of the inverter, antenna cables and television power cord.
3. Isolate the television, its power cord and antenna cables from the 12-volt power source by
running an extension cord from the inverter to the television set.
4. Coil the television power cord and the input cables running from the 12-volt power source to
the inverter.
5. Attach an AC interference filter or similar product between the inverter and the television power
cord. These filters are available at most electronic supply stores.
Note: Inexpensive sound systems may emit a "buzzing" sound when operated with an inverter. This is due to
the inadequate filters in the sound system. There is no solution to this problem.
WARNING
• Never attempt to operate the Pure Sine Wave Inverter from any power source other than a
12-volt battery.
• Always disconnect the inverter when not in use. Always ground the inverter before operating.
• Always ensure the power cable terminal connections run in parallel, Negative (-) to Negative (-)
and Positive (+) to Positive (+). Reverse polarity, DC power connections to the inverter must be
positive to positive and negative to negative. A reverse polarity connection ( positive to negative)
will blow a fuse in the inverter and may permanently damage the inverter. The fuse is not user
replaceable and you will void the warranty. Check these connections frequently to make sure they
remain secure. Loose connections cause excessive voltage drop and may cause overheated wires
and melted insulationUse the heaviest gauge wire available to connect the inverter to the power
source. When setting up the inverter, make certain that the inverter is positioned far away from
any potential source of flammable fumes or gases. While in use, make sure the inverter is
properly ventilated. Do not operate the inverter near flammable materials, fumes or gases.
• Make certain the power consumption of the appliance or equipment you wish to operate is
compatible with the capacity of the inverter. Do not exceed 650 W.
• When attempting to operate battery chargers, monitor the temperature of the battery charger for
approximately 10 minutes. If the battery charger becomes abnormally warm, disconnect it from
the inverter immediately.
• When operating the inverter with a Deep Cycle battery from a vehicle with it’s engine off, start
the engine every 30 to 60 minutes and let it run for approximately 10 minutes to recharge the
battery.
• In the event of a continuous audible alarm or automatic shutdown, turn the Inverter OFF
immediately. Do not restart the inverter until the source of the problem has been identified and
corrected.
