Jumper

The set nominal current of the current input transformers are checked on the input/output 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 ad-
ditionally 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.
