  1. When performing various operations or tests, the user should follow the relevant procedures andpay attention to the following items to ensure correct and safe use.

  2. According to the product identification input and output terminals are correctly wired.

  3. The line conductors shall comply with the relevant current standard values and the load current shallnot exceed the maximum protection current value of the protector.

  4. The neutral line N cannot be connected incorrectly and needs to be secure. The protector zero line Nis directly connected, and has no disconnection function.

  5. Before turning on the power, please check the wiring carefully.

  6. Do not touch live parts after the product is connected to the power supply to avoid electric shock.

  7. This protector has no short-circuit protection function and needs to be used with a miniature circuitbreaker. If the miniature circuit breaker protection is not used, the short-circuit current cannot bebroken when there is a short-circuit fault at the input or output of the protector.

  8. .Since the protector has a self-reset function, after the protector over-current is protected anddisconnected, the load electric appliance should be removed immediately, and the circuit line shouldbe checked. Otherwise, the protector will frequently turn on the load electrical appliance, andeventually the electrical appliance and the protector body will be damaged due to frequent switchingon and off for a long time.
