32 ClusterController-IA-en-10 Installation Manual
6.6 Connecting the Cluster Controller to a Speedwire Network
Requirements:
☐ The inverters must be equipped with Speedwire communication (depending on the feature: see
the installation manual of the inverter or the installation manual of the Speedwire/Webconnect
interface).
☐ The inverters must be cabled according to one of the possible network topologies (for
information on the possible network topologies as well as on the connection of the patch cable
to the Speedwire/Webconnect interface, see installation manual of the inverter or installation
manual of the Speedwire/Webconnect interface).
Additional required material (not included in scope of delivery):
☐ Depending on the network topology: patch cables (for cable requirements, see Section 6.3)

Do not connect the Speedwire network and the local network (LAN)
The Speedwire network is a separate network managed by the Cluster Controller. In case the
Speedwire network and the local network (LAN) are connected, a disturbance of both
networks is likely to occur.
• In order to ensure correct communication, do not connect the Speedwire network and the
local network (LAN) (the Speedwire bus and the Ethernet bus must not be connected to
the same switch, for example).
