Feature: 1. High End Motherboard: The inverter adopts high end motherboard, intelligent and practical, has strong protection and complete functions. 2. Full SMD Design: All internal components adopt SMD design, greatly increases the stability of the machine, provide excellent performance. 3. Flame Retardant ABS Housing: The housing is using industrial grade ABS plastic, has high impact and heat resistance, good flame retardant and comprehensive performance. 4. Simple Operation: The converter is designed with user friendly keyboard, equipped with digital display screen, easy and convenient for operation. 5. Good Heat Dissipation: Built in large heat sink, which is about 3 times larger than which of similar products, with small fan which has low noise when running, and assisting good heat dissipation. Specification: Item Type: Motor Variable Frequency Drive Material: ABS Storage Temperature: -25?? to +55?? Input Voltage: Three Phase 380-440V AC Output Voltage: Three Phase 0-440V AC. Package List: 1 x Motor Variable Frequency Drive1 x Manual Note: 1. Before wiring, please confirm whether the input power is in a power off state.2. The wiring operation shall be carried out by professional electrical engineering personnel.3. The grounding terminal must be grounded.4. After the emergency stop circuit wiring is completed, be sure to check whether the action is valid.5. Do not connect the output wire of the inverter with the shell, and do not short circuit the output wire.6. Please confirm whether the voltage of the AC main circuit power supply is consistent with the rated voltage of the inverter.7. Do not perform withstand voltage test on the inverter.8. Please connect the braking resistor according to the wiring diagram.9. Do not connect the power wire 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.12. The inverter that selects the reset and retry function should not be close to the mechanical equipment. Because it will restart suddenly when the alarm stops.13. After confirming that the running signal is cut off, the alarm can be reset. If the alarm is reset in the state of 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. While the power is on, do not change the wiring and do not remove or install the terminals.16. Inspection and maintenance can only be carried out after the main circuit power supply is cut off.17. Do not modify the inverter without authorization.
