Table 8-13 Jumper setting of relay contact for BO6.
The set nominal currents of the current input transformers are checked on the input/
output board C–I/O–2. 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
(input transformer T8).
The jumpers X71, X72 and X73 on the input/output board C–I/O–2 are for setting the
bus address and must not be changed. Table 8-14 lists the jumper presettings.
