transformer error and the monitoring switching can be blocked. The separate under-
voltage protection must be set non-delayed and should also evaluate the positive-
phase sequence system of the voltages (e.g. 7RW600).
Voltage at U
E
Input Depending on how U
E
is connected, it may be necessary to block the voltage mea-
surement of this input. A blocking can be generated with the CFC tool and combined
with the indication “VT Fuse Failure”.
