6.6 External current transformers
At motor currents above 120 A, external current
transformers must be used. Fit the transformers as
shown in fig. 12.
Note: Take the three measuring cables through the
three holes in the MP 204 five times per phase.
See fig. 13.
Note: The three current transformers must be fitted
in the same direction, and the measuring cables
must be connected in the same way.
