Terminal Description
UB, N1 Supply voltage:
2 Control voltage for downward movement during three-point mode
3 Control voltage for upward movement during three-point mode
B1, B2 Binary input / frost protection function
N2 Zero potential of signal X at 230 V AC
• If you run the actuator in three-point mode at 230 V you will
have to connect N2 before you can use X.
