Guidelines for installing the drive to a TT system
You can install the drive to a TT system under these conditions:
1.
There is a residual current device in the supply system
2.
The internal EMC filter is disconnected. If the EMC filter is not disconnected,
its leakage current will cause the residual current device to trip.
Note:
•
ABB does not guarantee the EMC performance, because the internal EMC filter
is disconnected.
•
ABB does not guarantee the functioning of the ground leakage detector built
inside the drive.
•
In large systems the residual current device can trip without a real reason.
