The set nominal currents of the current input transformer are checked on the input/out-
put board C–I/O–11. All jumpers must be set to the same nominal current, i.e. one
jumper for each input transformer (X61 to X64) and one common jumper X60.
However:
there is no jumper X64 for the version with sensitive earth current input (in-
put transformer T8).
For normal earth current inputs the jumper X65 is plugged in position “IE” and for sen-
sitive earth current inputs in position “IEE”.
The jumpers X71, X72 and X73 on the input/output board C–I/O–11 are for setting the
bus address and must not be changed. Table 8-17 lists the jumper presettings.
