External control voltage
You can control the Softstarter with an external 24 V DC
source from a PLC or similar, if necessary.
Connect the cables. See Figure 5.9 to use the internal
holding circuit, or Figure 5.10 to use an external holding
circuit.
WARNING
Use only 24 V DC to connect terminal 13, 14,
15, 16 and 17. Other voltages can damage the
Softstarter and the warranty will no longer be
valid.
