External control voltage
The softstarter can, if required, also be controlled with an
external 24 V DC source from a PLC or similar.
Connect the cables according to Figure 31 or Figure 32
depending on which type of control method is used.
WARNING
Terminal 13, 14 ,15, 16 and 17 should be
connected using 24V DC only. Other voltages may
damage the softstarter and the warranty may no
longer be valid.
