Technical Specification Part 2


  • Features
  1. RS422 / RS485 Industrial Voltage Surge Protector Yellow
  2. Quick response,Low voltage protection level
  3. Direct or indirect shield earthing
  • Installation Instruction
  1. The RS485 surge protection devices are connected in series to the protected device.
  2. The out terminal should be connected to the protected devices.
  3. There is a earthing terminal at input side,earth lead must be connected to the lightning earthing system,ideally using 2.5mm² cable. The cable should be as short as possible.
  4. Shields on the TS-RS485/5 can be grounded directly or indirectly. If grounded directly,the shield of the incoming cable is connected to terminal 8(IN) and the outgoing cable is connected to terminal 8´(OUT).

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.
