For outdoor application and/or in presence of adverse weather/strong electromagnetic events
it is advisable to use additional overvoltage protective devices.
In order to avoid earth 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.

The ethernet connection allows a direct data transfer to the ABB server
for monitoring purpose. When the inverter will be powered on, network
parameters are automatically set and the inverter starts transmissing
telemetry data to the Aurora Vision® CLOUD platform.
The connection of the ethernet communication cable must be made
on the specific connectors

If the inverters of the plant need to be connected in daisy chain or ring
configuration use both connectors.
The cable should be compliant to the following specification:
• Cable type: Patch or Cross type, 100BaseTx, CAT5e (or higher).
For outdoor application and/or in presence of strong electromagnetic
sources it is advisable to use shielded cables with metallic shielded
RJ-45 plug.
• UV-resistant if used outdoors
• Type of plug: metallic shielded RJ45
• The maximum length that can reach these cables is 100 meters, and
it is always advisable not to let them pass by the power cords to avoid
interference with data transmission.
• Maximum inverters number connected over one single daisy chain is 40
The two RJ45 connectors LAN1 and LAN2 are equivalent
ZGN.V2Q15.2
to each other and can be used interchangeably for the
input or for the output of the line in realising the connection
of the inverters.
