Guidelines for installing the drive to a TT system

The drive can be installed to a TT system under these conditions:

Residual current device has been installed in the supply system.

2. These screws have been disconnected. Otherwise EMC filter and

ground-to-phase varistor capacitor leakage current will cause the residual

current device to trip.

Because the EMC filter screws have been disconnected, ABB does not guarantee

the EMC category.

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 reason.
