For applications in which the motor's full load current rating is
greater than 360A, three additional current transformers with 5A
secondaries are required. The figure below illustrates the connection
of the current transformers to the converter module.
Figure 2.10 Current Transformer Connection to Converter Module
Current Transformer ➀➁
The current transformer (CT) ration must be programmed in the calibration group for proper current
measurement scaling. See page 5-2 for instructions on programming this parameter.
Another current transformer connects L2 and T2, and another connects L3 and T3.
The converter module, Cat No. 825-MCM20, must be used in these applications.
