Jumpers X71 through X73 on the input/output board C-I/O-9 serve for setting the bus address. Their position
may not be changed. The following table shows the preset jumper positions.

The rated currents of the measured voltage inputs can be set for each input transformer by jumpers on the
PCB. With default settings all jumpers are set to the same rated current (according to the order number of the
device).
•
For 3-phase applications and 1-phase transformers:
There are 3 measuring inputs for each of the three-phase measuring locations M3 and M4: Ι
L1M3
, Ι
L2M3
,
Ι
L3M3
, Ι
L1M4
, Ι
L2M4
, Ι
L3M4
.
The jumpers belonging to measuring location M3 (X61, X62, X63) must all be plugged to the rated
secondary current of the connected current transformers: “1A” or “5A”). Furthermore, the corresponding
common jumper (X82) has to be plugged to the same rated current.
The jumpers belonging to measuring location M4 (X65, X66, X67) must all be plugged to the rated
secondary current of the connected current transformers: “1A” oder “5A”). Furthermore, the corre-
sponding common jumper (X81) has to be plugged to the same rated current.
•
For 3-phase applications in 7UT635:
The auxiliary current input Ι
Z2
can be used for a fifth 3-phase measuring location M5. In this case set the
jumpers X64 and X83 both to the required rated secondary current for M5: “1A” or “5A”.
•
For 1-phase busbar protection:
There are 6 measuring inputs for 6 different measuring locations, i.e. the feeders 7 to 12: Ι
7
, Ι
8
, Ι
9
, Ι
10
, Ι
11
,
Ι
12
. Each input can be set individually to“1A” or “5A” or “0.1A” (X61, X62, X63, X65, X66, X67).
Only if measuring inputs Ι
7
to Ι
9
dhave the same rated current, will the common jumper X82 be plugged
to this current.
Only if measuring inputs Ι
10
to Ι
12
have the same rated current, will the common jumper X81 be plugged
to this current.
If different rated currents reign within the input groups, will the corresponding jumper be plugged to
“undef”.
For interposed summation transformers with 100 mA output, jumpers of all measuring inputs, including
the common jumpers, are plugged to “0.1A”.
•
For the 1-phase
auxiliary measuring input Ι
Z2
:
Jumper X64 and X83 are both set to the required rated secondary current for this single-phase current
input: “1A” or “5A”.
But: If in 7UT635 this input is used for a fifth three-phase measuring location M5, the jumpers must be
set (as mentioned above) to the secondary rated current of that measuring location.
•
For the 1-phase
auxiliary measuring input Ι
Z4
:
If this input is used as a “normal” 1-phase current input, set jumpers X68 and X84 both to the required
rated secondary current: “1A” or “5A”. Set X85 and X86 both to position 1-2.
If this input is used as a “high-sensitivity” 1-phase current input, jumper X68 is irrelevant. Set X84 to
“1.6A”. Set X85 and X86 both to position 2-3.
The following table gives a summary of the jumpers for the rated currents on C–I/O-9.
