Note.4-1.SW1(ON/OFF) Operation is as following;
RL1∼4:Load resistance(7W or more)
CL1∼4:Distribution capacity capacitor(3kV or more)
※1.When any of the load is opened, the alarm output becomes 5V.
※2.If the inverter detects open output connector for about 3 seconds it will shut down.
Input current 3 is an input current after operation stops.
