•
For 1-phase busbar protection:
Each input can be set individually. Only if measuring inputs Ι
plugged to the same rated current. Only if measuring inputs Ι
plugged to the same rated current.
If different rated currents are reigning within the input groups, the corresponding common jumper is
plugged to"undef".
For interposed summation transformers with 100 mA output, jumpers of all measuring inputs, including
the common jumpers, are plugged to 0.1 A.
