2. If no patch cable is connected to the inverter with integrated Speedwire communication and
Webconnect function, connect the patch cable to the network socket in the inverter (see
installation manual of the inverter).
3. Connect the Cluster Controller to the Speedwire network. For this purpose, observe the desired
network topology:
• When using a pre-configured patch cable, connect the patch cable to terminal X9 or X10.
• When using a patch cable that is to be configured by the user, mount the RJ45 plug
connector on the patch cable (see the manufacturer manual) and connect the patch cable
to terminal X9 or X10 of the Cluster Controller.
4. On the supplementary sheet for noting the connected devices, note the terminal to which the
node is assigned.
5. Deactivate the Webconnect function of the inverters after completion of the commissioning of
the Cluster Controllers (see user manual of the Cluster Controller).

Danger to life due to electric shock when opening the inverter
Lethal voltages are present in the conductive parts of the inverter.
If a patch cable has not yet been connected to the retrofitted Speedwire/Webconnect interface
in the inverter, perform the following steps:
• Disconnect the inverter from voltage sources on the AC and DC sides (see the inverter
installation manual). Observe the waiting time to allow the capacitors to discharge.
• Open the inverter (see inverter installation manual).
• Connect the patch cable to the retrofitted Speedwire/Webconnect interface (see the
installation manual of the Speedwire/Webconnect interface).
• Close the inverter (see inverter installation manual).
