– For Non-Regenerative drives only, remove the bolt and washers that
secure the U and W phase power terminals to the internal armature
circuit fuses and while pulling the U and W phase power terminals up
and into the drive, slide the AC Current Transducers off of the
terminal bus bars and out of the drive.
Step 4: Install the New AC
Current Transducers
Install the new AC Current transducers in reverse order of removal as
detailed in Step 3: .
Remove the Existing AC Current Transducers on page 5
Important: Note the color and location of the signal wires to ensure that
each wire is properly connected during installation. The wires
connected to the left CT are red and white and the wires
connected to the right CT are blue and black.
