A.2.3 Actuation Of A Line Contactor - Siemens SIRIUS 3RW55 Manual

A.2.3 Actuation of a line contactor
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.
