ACExC 01.2 Intrusive Modbus RTU
Electrical connection
Overvoltage protection (option)
Wiring diagram
1) The reversing contactors are designed for a lifetime of 2 million starts.
2) For the assignment of AUMA power classes, please refer to electrical data on actuator.
3) All input signals must be supplied with the same potential.
4) Not possible in combination with PTC tripping device
5) In combination with plug/socket connector KPH only
