    2,  Low voltage protection level

    3,  Direct or indirect shield earthing

    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.=
