5.8.1 Network Topology
The inverter has 2 Ethernet RJ-45 connectors enabling the
connection of several inverters in a line topology as an
alternative to the typical star topology. The 2 ports are
similar and can be used interchangeably.
NOTICE
Ring topology is only permitted if realised with Ethernet
switch supporting spanning tree.
