The set nominal current of the current input transformers are checked on the input/out-
put board C-I/O-2. All jumpers must be set for one nominal current, i.e. one jumper
(X61 to X64) for each input transformer and additionally the common jumper X60. But:
In the version with sensitive earth fault current input (input transformer T8) there is no
jumper X64.
Jumpers X71, X72 and X73 on the input/output board C-I/O-2 are used to set the bus
address and must not be changed. The following table lists the jumper presettings.
