Application Configuration
Basic Parameters
Application dependent parameters need to be configured so
that the monitoring and protection functions can be
implemented.
The C445UM Monitoring User Interface and Power Xpert
inControl software tool both walk users through an easy
Setup Wizard for these parameters.

Notes
1
These values may change depending on MM selection.
2
These values may change depending on MM use.
Advanced Parameters
Application dependent parameters are required for some
advanced applications. Users must set PT or CT Ratios if
external CTs or PTs are used. Additionally, users who want
to utilize motor torque and efficiency monitoring should set
Motor Rated Speed and Motor Rated Stator Resistance for
higher accuracy.
