Characteristics of Working
1 If the connection of L1 L2 and L3 phases are right the green light of the relay illuminates and the relay closes If they are wrong the yellow light of the relay illuminates Exchanging any two of the relay will accept the phase sequence and begin to work normally In this case that there occurs yellow light illuminated and relay unclose after the equipment works normally it should be a wrong connection of external circuit The relay has a function of protection against wrong connection
2 While any of these L1 L2 and L3 phases is Na phase the red light is lighted with the unlighted green light and the released relay While the voltage come back to normal it will immediately with lighted green light and relay
