OPERATION
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 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
i n v e rt e r.
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 re c h a rge the battery. We also re c o m-
mend that the device plugged into the inverter be turned off
b e f o re turning over the engine.
Although it is not necessary to disconnect the inverter when
t u rning over the engine, the inverter may momentarily cease
operation as the battery voltage decreases. When the invert-
er is not supplying power, and turned on, it draws very low
amperage from the battery (<0.35 A ).
