Technical Specification Part 2
If grounded directly,the shield of the incoming cable is connected to terminal 7(IN) and the outgoing cable is connected to terminal 7´(OUT).
Regularly inspect the operating status, especially after lightning/surge. Once the communication is off, electrician should check/replace the RS485 surge protection devices.
