Figure 3-17
The set nominal current of the current input transformers are checked on the input/output board C-I/O-11. The
jumpers X60 to X63 must all be set to the same rated current, i.e. one jumper (X61 to X63) for each input
transformer of the phase currents and in addition the common jumper X60. The jumper X64 determines the
rated current for the input Ι
models with sensitive ground fault current input there is no jumper X64.
For normal ground current inputs the jumper X65 is plugged in position "IE" and for sensitive ground current
inputs in position "IEE".
