2. Function of the electronic thermal protecting inverter
(1) When the load is within 103% of the inverters rated current, the operation continues.
When the load reaches 150% of rated current of the inverter, the operation will continue
for 1 minute. ( Refer to curve (1) of figure 3)
(2) After the activation of the electronic thermal switch, the inverter is shut off immediately.
The OL2 light will flash. To resume the operation, push RESET button or activate an external
reset contact on terminal 2.
