A.3.6 3Rw55 Soft Starter For Serial Starting With 3 Parameter Sets - Siemens SIRIUS 3RW55 Manual

A.3.6 3RW55 soft starter for serial starting with 3 parameter sets
Automatic restart.
Can cause death or serious injury.
If a starting command is pending, a restart will be triggered automatically after the reset.
This particularly applies if the motor protection has tripped. Dangerous states of the system
can result.
Reset the start command (e.g. via the PLC or switch) before performing a reset.
To do this, for example, link the group error output (terminals 95 and 96) into the control.
Note
Set the "Coasting down" coasting method on the 3RW55.
Note
In the case of increased operating sequences, set the dimensions for the 3RW55 soft
starters to at least one capacity level higher than the highest connected motor output.
