INSTALLATION INSTRUCTION 

1.  This RS485 Surge Suppression is 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.  Once the communication is off, electrician should check/replacethe SPD.=
