• To connect the signal and communication wirings, the communication and

control board

(28)

have to be extracted by removing the two M5 screws.

• After the connections has been made, re-insert the communication and con-

trol board

(28)

in the board tray and fasten the two M5 screws previosly re-

moved.

• Give each wire a pull test to confirm the connection is secure.
• Conduit must be attached using EMT rain tight fittings to maintain Type 4 en-

closure integrity.

Ethernet connection

The Ethernet connection allows a direct data transfer to the ABB server for moni-

toring purpose. When the inverter will be powered on, network parameters are au-

tomatically set and the inverter starts the transmission of telemetry data to the Au-

rora Vision® CLOUD platform.
The connection of the Ethernet communication cable must be made on the spe-

cific connectors

(40)(41)

located on the Communication and control board

(28)

The two RJ45 connectors LAN1 and LAN2 are equivalent to each other and can be

used for the input or for the output of the line connecting multiple inverters in a

daisy-chain.

The cable should be compliant to the following specification:

• Cable type: Patch or Cross type, 100BaseTx, CAT5e (or higher). For outdoor appli-

cation 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.

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 con-

nected to the RJ45 plug in only one side, the other side of the shield should be leaved floating. This could be guar-

anteed by crimping the shield or the screen of the ethernet cable to the RJ45 connectors only at one end of each ca-

bles.

Three topologies of ethernet connection to the router are available:

Ring configuration

ROUTER

Daisy chain configuration

ROUTER

Star configuration

ROUTER

The ring configuration is the preferred method to connect multiple units in order to allow reaching inverters also in case of single

unit failures.

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 the maximum length of the cable must be 100m between inverter – inverter and inverter – switch.
No initial setup is required to start data transmission to Aurora Vision.
Internet connection is required to use all the Aurora Vision remote functionalities.

sion account for remotely monitoring and managing the installed solar assets.
