Always tighten the Positive (+) and Negative (-) terminals when the inverter is in use otherwise a loose connection can overheat due to poor contact. Always make sure that the total rated power of the connected devices is less than 400W. Avoid placing the inverter in a location that receives prolonged direct sunlight or near to heat sensitive materials as the inverter can become warm during use.
