OPERATION
Note:
• The audible alarm may make a momentary “chirp”
when the inverter is turned OFF (O). The same alarm
may also sound when the inverter is being connected
to or disconnected from the 12 volt power source.
• The use of an extension cord from the inverter to the
appliance or equipment being operated will decrease
the power being delivered to the load. For best
operating results, the extension cord should be no
more than 50 feet long.
• Check frequently to ensure that the input and output
connections are secure. Loose connections may damage
the inverter, the power source, or may generate
excessive heat.

OPERATION
7. Run a ground from the Ground Lug Terminal at the
rear of the inverter to a proper grounding point using
the shortest practical length of 18 AWG wire.
Selection of the grounding point will depend on
where you are using the inverter. The ground wire may
be connected to the chassis of your vehicle or to the
grounding system in your boat or to the earth* if you
are operating the inverter in a remote location. Before
connecting to the ground, make certain that the
inverter is turned off.
Operating the inverter without properly grounding it
may result in electric shock.
* This ground can’t be the same ground as the AC
ground.
8. Confirm that the equipment or appliance to be operated
is turned off. Plug the equipment or appliance into one of
the AC receptacles on the front panel of the inverter.
9. Turn the inverter to the ON (I) position. Turn on the
equipment or appliance.
10. Plug the USB powered device into the inverter’s USB
power port.
