The generator set control board has a connector for Cat 5 Ethernet cable for connection to a

remote modem/router. See Ethernet/Email Interfacefor setup and operation.

Use Cat 5 Ethernet cable and 300V 18 gauge 75 °C wire for wiring the relay.

communication conductors between the generator set and transfer switch. Separation of Class 2

and power circuits should be maintained per Article 725.136 of 2008 NFPA 70: National

Electrical Code.
