Secondly, the output voltage of the low frequency inverter is 220 V AC, which is in a narrow space and in a movable state, so be extra careful. It should be placed in a safe place to prevent electric shock. When not in use, it is best to cut off its input power supply;
Third, do not place the low frequency inverter in the direct sun or near the outlet of the heater. The working ambient temperature of the inverter shall not exceed 40 ℃;
Fourth, the low frequency inverter will generate heat when working, so do not place objects near or on it;
Fifth, the inverter is afraid of water. Don't let it get wet or sprinkle water
