power unit (Page 259).
Note
Please note the wiring suggestions for the inside-delta circuit on the main circuit side.
Incorrect connection can result in faults.
Note
Risk of restart
The start command (e.g. issued by the PLC) must be reset prior to issuing a reset command,
because the motor attempts to restart again automatically if a start command is still active
following this reset command. This particularly applies if the motor protection has tripped.
For safety reasons, you are advised to integrate the group fault output (terminals 95 and 96)
in the controller.
