Fig.3-8 Schematic Diagram for Wiring of Analog Input Terminal 
 
B. Digital input terminal:   
        It needs to employ shielded cable generally, with wiring distance of no 
longer than 20 meters.   
    When valid driving is adopted, necessary filtering measures shall be 
taken to prevent the interference to the power supply.   
        It is recommended to use the contact control mode.   
B. Digital output terminal:   
When connecting to the load, the digital output terminal is directly 
connected between D0 and 24V, and there already exists continuous-flow 
absorption circuit inside the inverter. The load current is less than 50mA.If 
the load is too high, please transit via the replay.
