Example Wiring Diagram

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.
Breaker,
MCCB or GFI
Power source,
3-phase or
1-phase, per
inverter model
Intelligent inputs,
5 terminals

sure to use twisted
pair / shielded cable.
Attach the shield wire
for each signal to its
respective common
terminal at the
inverter end only.
