Note:

1. Before wiring, please confirm whether the input power supply is off.2. The wiring operation should 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 to the shell or 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 a withstand voltage test on the inverter.8. Please connect the brake resistor according to the wiring diagram.9. Do not connect the power wire to the U, V, W output terminals.10. Do not connect the contactor to the output circuit.11. Be sure to install the protective cover before power on. When removing the cover, be sure to unplug the power.12. The inverter that selects the reset and retry function should not be near mechanical equipment. Because it will restart suddenly when the alarm stops.13. After confirming that the operation signal is cut off, the alarm can be reset.If the alarm is reset while the signal is active, the inverter may start suddenly.Do not touch the inverter terminals.There is high voltage at the terminals, which is very dangerous.When the unit is powered on, do not modify the wiring or remove or install the terminals.Inspection and maintenance can only be performed after the main circuit power has been disconnected.Do not modify the inverter without authorization.
