Notes in main circuit wiring

(1)Wiring specifications, please implement wiring in accordance with electrical regulations; (2)Do not connect AC to the output of frequency converter (U, V, W), otherwise the frequencyinverterwill be damaged. (3)Power supply wiring, please try to use isolation line and pipeline, and the isolation line or pipelineendsgrounded. (4)Frequency inverter grounding wire can not be grounded together with welding machine, high-powermotor or high current load, please grounding alone; (5)Grounding please grounding correctly,grounding resistor less than 10Ω; Notes in wiring control circuit

(1)Please separate the control signal line from the main circuit line and other power lines. (2)To prevent misoperation caused by interference, use twisted or double shielded wires.,specification0.5~2mm² (3)Make sure the permissible conditions of each terminal, such as power supply, maximumpermissiblecurrent, etc

(4)The terminal wiring requirements, correct selection of accessories, such as: voltmeter, input powersupply, etc. After completing the wiring, please check it correctly and make sure that it is correct beforepoweris available. (5)After completing the wiring, please check it correctly and make sure that there is no mistakebeforepower can be turned on. 8. Parameter list
