The earth wire of the shielded cable is connected to RS485 communication module (PE). If the above standard wiring methods cannot meet the requirements, you can take the actions below: Wiring The multi-function input terminals use full-bridge rectifying circuit, as the below figure shows. PLC is the common terminal for X1~X5, FWD and REV. The PLC terminal can sink or source current. Wire connections X1~X5, FWD and REV is flexible and the typical wiring is shown below: ① Connection method 1 It is default to use the drive’s internal power source 24V, i.e. PLC connected with P24. If you want to use external power supply, make sure to remove the wire between PLC and P24. z Use isolated RS485 communication module; z If the noise is transmitted through the GND line to the drive or other devices, which results in malfunction of them, you may disconnect the GND lines. 4)Multi-function Input Terminal and FWD, REV EV1000 Series General Purpose Variable Speed Drive User Manual
