Figure 15-17 Wiring of the 3RW30 control and main circuits
(1) For the permissible values for the main and control voltage (dependent on the MLFB),
refer to chapter Technical data (Page 127) .
WARNING
(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
chapter 3RW30: LEDs and troubleshooting (Page 48)) are automatically reset when the
system return
s to normal. An automatic r
estart 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.
