External control voltage
The softstarter can, if required, also be used with an external
24 V DC source from a PLC or similar.
Connect the cables according to Figure 14 or Figure 15
depending on which type of control method is used.
Warning!
Terminal 4, 5, 6, 7, 8, 9, 10, and 11 should be connected
using 24V DC only. Other voltages may damage the
softstarter and the warranty may no longer be valid.
