(1) For the permissible values for the main and control voltage (dependent on the MLFB),
refer to chapter Technical data [Page 121] .
(3) Alternatively, the motor feeder can be assembled as a fuseless or fused version with type

(2) Automatic restart. Can result in death, serious injury, or property damage.
Faults caused by incorrect control voltage, a missing load, or a phase failure (refer to
Troubleshooting chapter) 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.
