1. Connect the Cluster Controller to the Speedwire network. Take the desired network topology
into account:
• When using a preassembled network cable, connect the network cable to network port
X9 or X10.
• When using a network cable that is to be assembled by the user, connect the RJ45
connector to the network cable (see the manual from manufacturer) and connect the
network cable to network port X9 or X10 on the Cluster Controller.
2. Write down the terminal assignment on the supplied supplementary sheet.
3. Deactivate the Webconnect function on the inverters after completion of Cluster Controller
commissioning (see the Cluster Controller user manual).
