User Manual of EM760 High-Performance Inverter 3.3.6 Wiring of analog output terminals The analog output terminals (M1 and M2) can be connected with external analog meters to represent multiple physical quantities, which are optional for selection by using F03.34 or F03.35. 3.3.7 Wiring of 485 communication terminals The communication terminals A+ and A- are the RS485 communication interfaces ofthe inverter. The online control ofthe host (PC or PLC controller) and inverter is performed through the connection and communication with the host. Connections of the RS485 and RS485/RS232 adapters to EM760 inverter are shown below.
