2. 6 The network wiring should be isolated from other high voltage wiring by routing the network in a separate conduit dedicated to the network 7 The network should be wired directly to the network comm port connectors No intermediate terminations or splices should be used The network should be wired in a direct connect topology as shown not in multi drop or cluster topologies Note The network comm interface connectors contain two sets of and terminals The two sets of terminals are tied together internally on the board to to and are provided as tie points to ease wiring Communications across the network will continue even if one of the nodes has failed provided all the connectors are installed in their respective board However if a connector is pulled from it s board communications to the boards downstream will be lost the internal tie point will be broken If it is desired this situation can be avoided by wiring the connector as shown in figure 2 S3012 User s Manual SYSTEMS Electronics Group 62 SECTION 9 INSTALLATION 3012 53012 W SPB3012 1 W SPB3012 1 BELDEN CABLE 9182 OR EQUIVALENT pu X BLK A Lim a NOTE SHIELD TIED TO EARTH GROUND AT ONE BOARD er ONLY S3014 1 TO OTHER S3012 S amp S3014 S BLK TOTAL OF 32 MAX YEL 150 ohm TERMINATING RESISTOR USED AT EXTREME ENDS OF NETWORK Figure 1 Typical Network Wirin 3012 W SPB3012 1 TO OTHER S3012
