The rated currents of the measured current inputs can be determined for each analog
input. With default settings all jumpers are set to the same rated current (according to
the order number of the device).
The measuring inputs available depend on the intended use and the device variant.
For the above slots, the following applies to all devices:
• For 3-phase applications and 1-phase transformers:
There are 3 measuring inputs for each of the three-phase measuring locations M1
and M2: I , I , I
L1M1 L2M1
The jumpers belonging to measuring location M1 (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 M2 (X65, X66, X67) must all be
plugged to the rated secondary current of the connected current transformers: „1A
"or „5A"). Furthermore, the corresponding common jumper (X81) has to be plugged
to the same rated current.
• For 3-phase applications in 7UT635:
The single-phase auxiliary current inputs I
phase measuring location M5. In this case set the jumpers X64, X68, X83 and X84
all to the required secondary rated current for M5: „1A" or „5A".
Set X85 and X86 to position 1-2.
• For 1-phase busbar protection:
There are 6 measuring inputs for 6 different measuring locations, i.e. the feeders 1
to 6: I , I , I , I , I , I
1 2 3 4 5 6
X67): „1A" or „5A" or „0.1A".
Only if the measuring inputs I
this rated current.
Only if the measuring inputs I
this rated 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 measur-
ing inputs, including the common jumpers, are plugged to „0.1A".
• For the single-phase auxiliary measuring input I
Jumpers X64 and X83 are both set to the required rated current in accordance with
the connected current transformer: „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 single-phase auxiliary measuring input I
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" current input, jumper X68 is irrelevant. Set
X84 to „1.6A". Set X85 and X86 both to position 2-3.
But: If in 7UT635 this input is used for a fifth 3-phase measuring location M5, set
the jumpers to this rated secondary current (see above). X85 and X86 must then be
set to position 1-2.
