VIII. Announcements

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.​​​​​​​

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

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.​​​​​​​

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.​​​​​​​

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

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

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.​​​​​​​

.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.​​​​​​​

This protector has no isolation function. Please use the miniature circuit breaker when using it, anddisconnect the front-end breaker switch when repairing the circuit line.​​​​​​​

Please note! When the undervoltage breaking time is greater than 0.3 seconds, theprotector does not open after the power failure. (The power failure of the MCU doesnot work after 0.3 seconds of power failure)​​​​​​​

After the overcurrent exceeds 5 times within the specified time, the protector lockwill not automatically restore the power supply. You must manually press the set buttonto unlock the power supply, which can effectively protect the device from frequendisconnection caused by not releasing the overcurrent in time.
