4.3 How to connect communication cable
4.3.1 Electric(twisted pair) cable
Cable for electric network connection uses only No.6 and No.7 of the connector pin, No.6 signal of
communication module connector A is connected to No.6 of communication connector B, and No.7 of
connector A is connected to No.7 of connector B. Body of connector(metal : electrically conductive) is
connected with other module by shielding wire, and bypasses external noise, etc., so connector of both
side should be connected with shielding wire, and contact with high voltage and high current should not
be allowed.

4.3.2
Electric (twisted pair) cable connector connection
Connector is accessory parts which connects electric network of fieldbus module, and it should
be connected as a method in Figure 4.3.2(A). It should be noted that shielding wire of cable
should be connected to metal part of connector by soldering, and the other. Data
transmission/receive is impossible if shielding wire is not connected.
