Applies only for operation in the active mode. For line supplies 3-ph 480 VAC ±10%, it must be
2)
checked as to whether the motor systems are suitable for this mode.
If a TN system is required on the secondary side, for example, when using a Wideband Line
Filter, a transformer with grounded neutral point must be used. However, the loop resistance
must be small enough to trigger the fuses as fast as required. Also see Chapter Overcurrent
protection using line fuses and circuit breakers (Page 51).
Note
System fault level at the infeed point
In order to comply with EMC limit values, Category C2 according to EN 61800-3, the system
fault level at the infeed point must be at least a factor 70 higher than the rated power of the
integrated infeed.
Vector group
Any vector group with the neutral point brought out on the secondary side.
