Input Wiring
Examples
Intelligent terminals [1], [2], [3], [4] and [5] are identical, programmable inputs for general use.
The input circuits can use the inverter's internal (isolated) +24V field supply (P24) to power the
inputs. The input circuits connect internally to [PLC] as a common point. To use the internal
supply to power the inputs, use the jumper as shown. Remove the jumper to use an external
supply, or to interface to a PLC system (or other) that has solid state outputs. If you use an
external supply or PLC system, its power return must connect to the [PLC] terminal on the
inverter to complete the input circuit.
The following four input configurations are available to interface the inverter inputs to switches
or the outputs of another system, such as a PLC.
