(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
of coordination 1 or 2. For the assignment of fuses and switching devices, refer to chapter
Technical data [Page 121]

(2) Automatic restart.
Can result in death, serious injury, or property damage.
The start command (e.g. issued by the PLC or switch S1) must be reset prior to issuing a
RESET command because the motor attempts to restart again automatically following this
RESET command if a start command is still present. 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.
Note
(4) Idle time until restart.
Owing to the intrinsic protection (3RW), an idle time of at least five minutes must be allowed
prior to restarting if the device is switched on and off by means of the control voltage under
field conditions.
