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.
Breaker, MCCB
or GFI
Power source,
3-phase or
1-phase, per
inverter model
Intelligent inputs,
7 terminals
Forward
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
4.7kΩ
Thermistor
Short bar
(Source type)
GND for logic inputs
Meter
Meter
Analog reference
0~10VDC
4~20mA
Pulse train input
24Vdc 32kHz max.
GND for analog signals
