The schematic diagram below provides a general example of logic connector wiring, in 
addition to basic power and motor wiring covered in Chapter 2. The goal of this chapter is to 
help you determine the proper connections for the various terminals shown below for your 
specific application needs.

NOTE: For the wiring of intel-
ligent I/O and analog inputs, 
be sure to use twisted pair / 
shielded cable. Attach the 
shield wire for each signal to 
its respective common termi-
nal at the inverter end only.
