3.1.3 Remote Switching and MODBUS Interface

The generator can be remotely controlled from either an external digital input (e.g. PLC) or via a MODBUS connection in a SCADA system or
similar. Refer to "Customer Configuration" on page 14 of this guide for details on how to enable the remote switching function. Once the remote
switching function has been enabled the local start control will no longer function, however it will initiate Standby.
Wiring the connector
The connector supplied with the generator will accept 7-9mm cable, wire size 0.5-2.5mm
Screened cable is recommended when connecting to MODBUS.
Strip 22mm of insulation from the cable, and strip 4mm from each wire.
•
Use the sealing cap to remove the locking ring and withdraw the plug insert.
•
Remove the gland nut, gland cage, and gland from the main body and slide them over the cable.
•
Slide the cable into the main body and connect the wires to the plug insert as detailed.
•
Gently pull the cable backwards so that the plug insert is located in the locking cap.
