Hardwarephysicalconnection

Inthefollowingchapter,physicalconnectionofthehardwarewillbeexplained.

Fieldbusgrounding

For AC500, which has opto‐isolated COM interfaces, it is recommended not to connect the ground. For AC500‐

eCo, where the COM interfaces are not opto‐isolated, it is recommended to connect the ground at one place,

typicallyinthebusmaster.Forconnectionexamples,seechapter“Installationexamples”.

Fieldbusshield

TheshieldshouldalwaysbeconnectedinaModbusRTUline.ThepurposeoftheshieldistoprotectagainstEMC

disturbancesandreflectiononthebusline.Forconnectionexamples,seechapter“Installationexamples”.

Endtermination

 Purpose:Toavoidsignalreflections.

 Resistorsize:120Ohms,¼W.

 Wheretoconnect:Oneresistorineachendofthebusline(firstandlastnode).

Pullup/pulldownresistors

 Purpose:Tokeepadefinedhighlevelonthebuswhilethereisnodataexchange.

 Resistor size: Depends on bus master (COM) voltage level. 470Ωfor AC500 (5 V output) and 270Ωfor
