2.2. The inverter should be far away from the fire sources and electric shock, and failure to follow the wiring
requirements or the use of wires that do not comply with the standards may cause the abnormal operation or
damage to the inverter.
2.3 Because the inverter itself includes components that can easily generate arc, it is forbidden to install the
inverter in flammable or explosive environments and nearby the equipment without fire protection, including:
gasoline generators, inflammable fuel barrels or other component systems located near the fuel.
2.4. When installing the battery cable, if your skin or clothing touches the acidic substance of the battery, please
rinse it immediately with water, and go to the hospital for treatment in time if the circumstances are serious.
2.5 Do not put metal tools on the battery, because this is likely to cause the battery or other electronic components
explode due to fire sparks generated by short circuit.
2.6 t is strictly forbidden to put small metal items such as iron needles and iron pins into the product; far away
from water sources, and do not spray water on the product or in the product.
2.7 It is forbidden to allow the children operate this product, or touch the terminal posts or output ports of this
product with their fingers, so as to avoid the risk of electric shock.
2.8 Please turn off the AC and DC power before the maintenance, cleaning or connection of any circuit of the
inverter; do not dismantle the inverter, because the internal capacitor still stores electrical energy after all power
supplies are disconnected.
3. Protection Function
3.1. Input undervoltage protection: when the input battery voltage is too low, the red indicator light is on, and an
alarm sound is issued at the same time; the AC output will automatically turn off, indicating that the battery
voltage is lower than the protection setting value, and that the battery needs to be charged. The input voltage
protection setting values are as follows:
DC12V product input voltage is below 10±0.5V;
DC24V product input voltage is below 20±1V;
DC48V product input voltage is below 40±2V.
3.2. Input overvoltage protection: When the battery voltage is too high, FAULT red indicator light will be on, and
an alarm sound is issued at the same time; the AC output will automatically turn off, indicating that the battery
input voltage is higher than the protection setting value. The input voltage protection setting values are as follows:
