CONNECTION DIAGRAM OF UNIT
For wiring of the external input terminals, refer to the Connection Diagram for Each Setting System.
Use a transformer to obtain a 200/220V of the control power when other value of the power supply voltage is
supplied for the main circuit. Align the polarities between the main and control circuits for wiring.
