2 Measurement System
The KSR-V measurement system provides 7 input channels:
For Voltage measurement the connectors L1, L2, L3, (N) have to be connected witch the corresponding
points of the supervised system. The connection of N is not necessary in all cases. If left open, an artificial N
potential is provided by an internal resistor network.
Voltage measurement channels V1-4 via voltage measurement transformers (secondary connections open
delta). A maximum of 4 voltage channels is available.
The KSR-V provides separate input terminals for the device supply voltage. It has to be connected regarding
the specifications written on the type label. The supply voltage can also be connected to the power system to
be measured.
