• Voltage is scaled to the primary amplitude; therefore, the different sized PT secondaries are
possible.
• The minimum voltage for direction and frequency solving is 20.0 %U

.
• U< dead limit is not in use when set to 0 %U

.
• When SYN3 is used, SYN1 and SYN2 must have the same reference voltage.
• In 3LN mode the synchronization to the L-N and L-L voltages is possible. In 3LL/2LL modes
the synchronization is only supported to the L-L voltage.
