Rockwell Automation 20D-MDI-C1 Multi-Device Interface Option Board for PowerFlex 700S Drives - Manual (Page 10)

10 Multi-Device Interface Option Board for PowerFlex® 700S Drives
Step 8: Wire the MDI
Option Board Terminal block P1 contains connection points for a linear sensor, rotary
encoder and registration strobe. This terminal block resides on the MDI
Option board
.
TIP: On Phase I drives, remember to route wires through the
sliding access panel at the bottom of the Control Assembly.
