1. Check List Before Use

Please make sure that the product specifications are the same as ordered.
Check to ensure that no damage has occurred during delivery, and that there are no defects or missing items.

2. Operation Time Set-up
TIME: this refers to the time that operation of the relay is delayed by the current of power leakage that is greater than the set current. Precise set-up is required, since it works after the TIME is passed. The operating time is as marked as on the scale of the control knob.

(1) When setting up, consider the safety time of the motor and other machines.
(2) Operating Time can be set-up, and is controllable in a range of 0.1~3 seconds.
(3) Since the time is fixed, operating time will be tripped after the TIME is passed from the moment when the current from power leakage occurs, at which time the red LED will illuminate.

3. Rated Current Set-up

(1) Set the current control knob to a safe level

4. To Confirm Operating

(1) While only the power is on, if the TEST button is pressed, the power leakage indicator lamp (O.L) on the power leakage protective relay will illuminate dimly. After the set O-TIME is exceeded, the O.L will illuminate, the green power lamp will turn off and it will trip.
(2) When it trips, press the RESET button to recover the initial state. The power leakage over current indicator lamp turns off, and the power lamp illuminates.
