thernet connection configuration
In order to avoid ground loop (that could create communication issues) the shield of any
Ethernet cable must be connected to the RJ45 plug in only one side, the other side of the
shield should be leaved floating. This could be guaranteed by crimping the shield or the screen
of the ethernet cable to the RJ45 connectors only at one end of each cables.
Three topologies of ethernet connection to the router are available:
Ethernet connection - Ring configuration
Customer router
Ethernet connection - Star configuration
Ethernet connection - Daisy chain configuration

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
