Feature:1. Full Featured: Intelligent and efficient, extremely strong protection performance, full featured, can effectively make the operator's work efficiency.2. Surface Mounted Devices Design: All internal components are designed with surface mounted devices design, which greatly increases the stability of the machine and allows the safety of the machine and the operator to be guaranteed.3. Flame Retardant: This inverter is made of industrial flame retardant ABS plastic, which is highly impact resistant, highly heat resistant, flame retardant and has good overall performance.4. Humanized Design: Humanized keyboard design, digital display, easy to operate, simple and clear, brings a lot of convenience for the normal use of the user.5. Oversized Heat Sink: oversized heat sink with small fan, about 3 times larger than similar products, small fan to ensure low noise while assisting good heat dissipation.Specification:Item Type: Variable Frequency InverterMaterial: ABSStorage Temperature: -25~+55Input Voltage: Three phase 380-440V ACOutput Voltage: Three phase 0-440V AC.Package List:1 x Inverter1 x Instruction ManualNote:1. Before wiring, please make sure that the input power is in the power off state.2. Wiring operation, please professional electric engineering personnel to carry out.3. Please be sure to ground the grounding terminal.4. After the wiring of emergency stop circuit is completed, please make sure to check whether the action is effective.5. Do not connect the output line of the inverter to the shell, and do not shortcircuit the output line.6. Please make sure that the voltage of the AC main circuit power supply is the same as the rated voltage of the inverter.7. Do not conduct voltage withstand test on the inverter.8. Please connect the braking resistor according to the wiring diagram.9. Do not connect the power line to the output U, V, W terminals.10. Do not connect the contactor to the output circuit.11. Be sure to install the protective cover before powering on. When removing the cover, be sure to disconnect the power supply.12. Do not use the inverter with the reset and retry function near mechanical equipment. Because it will start again suddenly when the alarm stops.13. Confirm that the alarm is reset only after the operation signal is cut off. If the alarm is reset under the running signal, the inverter may start suddenly.14. Do not touch the terminals of the inverter, there is high voltage on the terminals, which is very dangerous.15. Do not change the wiring and terminal disassembly during poweron.16. Cut off the main circuit power before inspection and maintenance.17. Do not modify the inverter without permission.
