3Rw40 2 To 3Rw40 4 Emergency Stop And 3Tk2823 Safety Relay - Siemens SIRIUS 3RW30 Manual

(1) For the permissible values for the main and control voltage (dependent on the MLFB),
refer to chapter Technical data [Page 121] .
(2) Automatic restart. Can result in death, serious injury, or property damage.
- If the 3TK28 is reset
Faults caused by incorrect control voltage, a missing load, or a phase failure (refer to chapter
3RW30: LEDs and troubleshooting [Page 44]) are automatically reset when the system
returns to normal.
An automatic restart is initiated and the 3RW restarted if a start command is present at the
input.
If you do not want the motor to start automatically, you must integrate suitable additional
components, e.g. phase failure or load monitoring devices, into the control and main circuits.
(3) Alternatively, the motor feeder can be assembled as a fuseless or fused version with type
of coordination 1 or 2. For the assignment of fuses and switching devices, refer to chapter
Technical data [Page 121]
