to Enabl. w. comp. (available with compounding). Do not use compounding in lines
with series capacitors!
For the trip circuit supervision set at address 140 Trip Cir. Sup. the number of
trip circuits to be monitored: 1 trip circuit, 2 trip circuits or 3 trip
circuits, unless you omit it (Disabled).
If the device is connected to voltage transformers, set this condition in address 144V-
TRANSFORMER. The voltage dependent functions, such as the directional time over-
current stages or the determination of voltage related measuring values can only be
activated by the device if voltage transformers are connected.
If a power transformer is located within the protected zone, set this condition in
address 143 TRANSFORMER order option). The transformer data themselves are then
polled when parameterizing the general porotection data (see 2.1.4.1).
