[Question]:AVD300 connect to S130,Is it necessary to set the normally open or normally closed
 [Question]: I use the AVD300 to monitor the three-phase power-off, and connect to the S130. Is it necessary to set the normally open or normally closed on the S130?
 [Answer]: Monitor the three-phase electrical power-off output normally open signal. (If the 220V mains is cut off, the output is a normally closed signal)
