OR AROUND WATER. 

MEASURING THE AC VOLTAGE 

The output waveform of the AC inverter is a Pure Sine
Wave.

SAFETY PRECAUTION 

Do not open the case of the inverter.  The high voltage
inside the unit is the same type of power as your 
electrical outlets at home. 

Do not let the cord of the inverter or any appliance’s cord 
get wet.

Do not operate the inverter in or around water.  The 
voltage of the unit makes electrical shock hazard if 
operated in wet conditions.

Do not connect the AC inverter directly to another AC 
power source.

Keep it away from children, the inverter produces power
just like your AC wall outlets at home and should be 
treated seriously.

Allow at least 1 inch of clearance around the inverter for
airflow.

If you operate the inverter in a moving vehicle, you need 
to secure the inverter to prevent it from shifting around
while the vehicle is moving.

If there is anything wrong with the inverter, disconnect all 
of the power.
