ABB PVS-100-TL-B-SY2 Product Manual page 88

Three topologies of ethernet connection to the router are available:
The ring configuration is the preferrable way to connect the units in order to allow reaching
inverters in case of single inverter fault.
In case inverters are connected to the networking switch with a ring topology is recommended
to enable SPT protocol on the switch (Spanning Tree Protocol SPT (IEEE 802.1D) is enabled
by default on inverters).
On each configuration of connection the maximum length of the cable
must be 100m maximum between inverter – inverter and inverter –
switch.
For further information on the Ethernet connection refer to the Local Area Network standard
IEEE802.3.
