Safety Information
WARNING: Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire, and/or serious injury.
- Ensure the inverter is used in a well-ventilated area.
- Do not expose the inverter to rain or wet conditions.
- Do not operate the inverter if it has received a sharp blow, been dropped, or otherwise damaged.
- Keep children and unauthorized persons away from the inverter during operation.
- Only use compatible Dewalt 20V/60V Lithium-Ion batteries.
- Remove batteries when the power inverter is not in use to prevent accidental discharge or damage.
- Do not attempt to power appliances exceeding the inverter's maximum output of 350W. Overloading can cause the unit to shut down or be damaged.
Built-in Safety Protections:
- Low-Voltage Protection: Protects the battery from excessive discharge. When the battery voltage is lower than 15.5V, the inverter starts the protection program, cutting off AC power and shutting down.

Image: Explanation of Low-Voltage Protection, showing the inverter's automatic shutdown mechanism when battery voltage falls below 15.5V to prevent over-discharge.
- Over-Voltage Protection: Protects electrical appliances from burning out. The AC output automatically turns off if an over-high input voltage is detected. The battery voltage needs to be lowered below 21V before use.

Image: Explanation of Over-Voltage Protection, detailing how the AC output is automatically disabled if the input voltage is excessively high, requiring battery voltage to be below 21V for operation.
- Over-Power Protection: When the power drawn by electrical appliances exceeds the maximum available power (350W), the AC output automatically turns off. The indicator light on the inverter will flash and beep.

Image: Explanation of Over-Power Protection, showing the inverter's response (AC output off, flashing light, beep) when connected appliances exceed the 350W limit.
- Short-Circuit Protection: If the AC output is short-circuited, the AC output will automatically turn off. Resolve the problem and restart the unit.

Image: Explanation of Short-Circuit Protection, indicating that the AC output will automatically shut down if a short circuit is detected, requiring problem resolution and a unit restart.
- Over-Temperature Protection: When using AC output, the unit generates heat. If the temperature becomes too high, the built-in fan automatically starts to dissipate heat. This is normal operation.
