External power supply Figure 3-18 Wiring of Multi-function Output Terminal 1. An antiparallel diode must be added, in order to use an internal power supply (as shown in Figure 3-18-a). 3.3.7 Analog Output Terminal Wiring External analog table of analog output terminals M1 and M2 may indicate multiple physical quantities. Select (0 - 20 mA) or (0 - 10 V) by DIP switch; M1 corresponds to S2; M2 corresponds to S3. Wiring of DIP switch and terminal is as follows:
3.3.8 Wiring of Communication Terminal Communication terminals A+ and A- are RS485 communication interfaces of inverter. Realize networking control of host controller (PLC or PLC controller) and inverter by connecting to host controller for communication. RS485, RS485/RS232 converter and EM600 inverter are wired as per Figures 3-19, 3-20 and 3-21. RS485 terminal of single inverter directly connects to host controller for communication:
