5.7.1 Network Topology
The inverter has two Ethernet RJ45 pin connectors that
enable the connection of several inverters in line topology
(as an alternative to the usual star topology).
INFORMATION
Ring topology (C in figure 5.5) is only permitted if
realized with Ethernet switch supporting spanning
tree.
