4-2-1 Example Wiring Diagram
The schematic diagram below provides a general example of logic connector
wiring, in addition to basic power and motor wiring converted in Chapter 2.
The goal of this chapter is to help you determine the proper connections for
the various terminals shown below for your application needs.

NOTE:
For the wiring of intelligent
I/O and analog inputs,
be sure to use twisted
pair / shielded cable.
Attach the shielded wire
for each signal to its
respective common
terminal at the inverter
end only.
Input impedance of
each intelligent input is
