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 of the Instruction Manual.
The goal of this chapter is to help you determine the proper connections for the various
terminals shown below for your application needs.
Breaker, MCCB
or GFI
Power source,
3-phase or
1-phase, per
inverter model
Jumper wire
(Sink logic)
Thermistor
Intelligent inputs,
7 terminals
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
