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

Precise set-up is required, as it operates after O-Time. The time is as marked on the control knob.
(1) Operating Time Set-up
O-TIME is controllable in a range of 0.2~30 seconds.
(2) It will trip when O-TIME is exceeded during a power surge while operating.

3. Rated Current Set-up

(1) Run the generator after setting up the required voltage by turning the voltage control knob.
(2) To determine the actual voltage while operating, slowly turn the knob counter-clock wise. The actual voltage (100%) has been met when the power surge indicating red lamp (O.L) turns off.

4. To Confirm Operating

(1) While the power is on, if the TEST button is pressed, the power surge indicator lamp on the generator protect relay (O.L) will dim, and then brighten after the set O-TIME has been reached, as the power lamp turns off and it trips.
(2) When it trips, press the RESET button. The power surge indicator lamp will turn off, and the initial state will be recovered.
