ADDITIONAL FEATURES
Automatic Shut Down & Related Safety Features.
Each inverter has an unique LED indicator warning light
system which operates in conjunction with the automatic
shut down feature. These indicator lights operate as follows:
GREEN LED: System ready.
RED LED: System overload/automatic shut down.
Your inverter will shut down automatically when any of the
following problems occur:
1. The power input from the battery drops below
10 volts.
2. The power input from the battery exceeds 15.5+/-0.5
volts.
3. The continuous draw of the appliance or equipment
being operated exceeds the design parameters of the
inverter.
The inverters are also equipped with the following additional
safety features:
1. Thermal Cut Off
Automatic shut down if internal temperature exceeds safe
design parameters.

does blow, turn off and disconnect the appliance or
equipment from the inverter immediately, repair the related
problem and replace the fuse(s). The internal fuses are
replaceable, however only electronically knowledgeable
people should attempt fuse replacement.
Note:
•
Make certain to correct the source of the overload
which caused the blown fuse before turning your
inverter back ON (l).
The Power Source.
When the engine is off, most batteries will provide an ample
power supply to the inverter for one to two hours. The actual
length of time is a function of several variables including the
age and condition of the battery and the power demand
being placed on it by the equipment being operated with the
inverter.
If you are using the inverter while the engine is off, we
recommend you start the engine every hour and let it run for
at least 10 minutes to recharge the battery. We also
recommend that the device plugged into the inverter be
turned off before turning over the engine.
Although it is not necessary to disconnect the inverter when
turning over the engine, the inverter may momentarily cease
operation as the battery voltage decreases. When the inverter
is not supplying power, and is turned on, it draws very low
amperage from the battery (<0.70 A ).
