If the ratio of the current transformer is either 2500:1 or 4000:1
The next table lists some burden resistor settings based on two types of current
transformers (2500:1 and 4000:1) and some values for the nominal current I
dN
.
As long as the nominal current of the power stack is close to these cur-
rents and the current transformers are identical as listed below this op-
tion for coding the current should be used!
In such a case remove the jumpers on the SDCS-PIN-51 board according to the
current selected and set parameter S ConvScaleCur (97.02) to exactly that se-
lected rated current.

Hint:
In case a DCS800-R0x will be used to replace a DCR500B or DCR600 keep the
coding of the SDCS-PIN-51 board as done in the past and set parameter 97.02
exactly to that value the SDCS-PIN-51 board was coded.
The zero current detection is done on the controller board SDCS-CON-4. Because
of that the resistors available for that function need not to be coded!
