Feature:1. EFFICIENT MOTHERBOARD: Using excellent motherboard, intelligent and efficient, with strong protection performance and complete functions2. FULL SMD: All internal components adopt SMD design, which greatly increases the stability of the machine3. EXCELLENT ABS: Industrial flame retardant ABS plastic material has high impact resistance, high heat resistance, strong flame retardancy, good comprehensive performance4. EASY TO USE: Adopt humanized keyboard design, with clear digital display, easy for you to operate, simple and convenient5. LOW NOISE WITH GOOD COOLING: The super large heat sink with a small fan, which is about 3 times larger than the heat sink of similar products. The small fan ensures low noise and assists good heat dissipationSpecification:Item Type: Variable Frequency DriveModel: LK320 seriesMaterial: ABSStorage Temperature: -25~+55.Package List:1 x Variable Frequency Drive1 x User ManualNote:1. Before wiring, please confirm whether the input power is in a power off state.2. For wiring work, please ask 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 cord 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 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. During power on, do not change wiring and terminal disassembly.16. Cut off the main circuit power before inspection and maintenance can be carried out.17. Do not modify the inverter without authorization.
