The input/output board C-I/O-2 carries the following measured current inputs:
• For 3-phase applications and 1-phase transformers:
There are 3 measuring inputs for the three-phase measuring location M3:
I
L1M3
,
I
L2M3
,
I
L3M3
. The jumpers X61, X62, X63 belonging to this measuring location must
be plugged all to the rated secondary current of the connected current transformers:
„1A “or „5A“. Furthermore, the corresponding common jumpers (X51 and X60) have
to be plugged to the same rated current.
• For 1-phase busbar protection:
There are 3 measuring inputs for 3 different measuring locations, i.e. the feeders 7
to 9:
I
7
,
I
8
,
I
9
. Each input can be set individually (X61, X62, X63) to „1A“, „5A“ or
„0.1A“. Only if the measuring inputs
I
7 to
I
9 have the same rated current, the
common jumpers X60 are plugged to this rated current.
If different rated currents (X51 and X60) are reigning within the input group, the po-
sition of the common jumpers (X51 and X60) is irrelevant.
• For the additional single-phase measuring input
I
X2
:
Jumper X64 is set to the required rated current for this 1-phase current input: „1A“
or „5A“.
