Installation Precautions
1, the automatic reclosing power protector is installed on the wall or in the host box, avoid direct rain, sunshine.
2、Connect this product to the bottom of the circuit breaker (or gate switch), power supply to the input terminal, load to the output terminal.
3、If the red indicator light is on after 10 seconds of closing the power supply, it indicates that there is a corresponding fault in the line, turn off the switch for 10 seconds and then close it again. If still can't close the gate to send power, it indicates that the leakage current in the line exceeds the specified value, or there is overcurrent/short-circuit phenomenon in the line should be shut down all the loads, find out the reason immediately and remove the fault before sending power.
4, this automatic reclosing power protector can replace the existing leakage switch and circuit breaker in the installation of this automatic reclosing power protector, can not be used at the same time with the existing ordinary leakage switch, should be removed from the installed leakage protection switch.
