5.11.2 Connections to the communication and
control board
The communication and control signals cables must be connected
to the communication and control board
(28)
inside the wiring box.
To reach the board, on the right side of the wiring box, there are
4xM25 cable glands (cable range accepted 10-17mm)
(12)
.

ATTENTION –
A
The connection of the communication and
control signal cables should be done with no over-length of
the above mentioned cables. Moreover the communication
and control signal connection cables should not be in contact
with live parts.
ATTENTION –
A
Please ensure that all unused signal cable
glands
(12)
are properly sealed by the IP66 plastic cap (pre-
installed on cable glands).
As an alternative, the standard gasket of the M25 cable glands can
be replaced with the two-hole gasket (supplied in the wiring box
installation kit), that accepts two separate cables with a diameter of
6mm. If a hole is not used, it is necessary to install a plug (supplied
plastic cylinder) to ensure the inverter’s sealing.
Check the tightness of the signal cable glands
(12)
(tightening
torque 7.5 Nm) at the end of wiring operations.
5.11.3 Ethernet connection
The Ethernet connection allows a direct data transfer to the Fimer
server for monitoring purpose. When the inverter will be powered
on, network parameters are automatically set and the inverter
starts the transmission of telemetry data to the Aurora Vision®
CLOUD platform.
The connection of the ethernet communication cable must
be made on the specific connectors
(39)
(40)
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.
ATTENTION –
A
If the inverters 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.
ATTENTION –
A
For outdoor application and/or in presence
of adverse weather/strong electromagnetic events it is
advisable to use additional overvoltage protective devices.
ATTENTION –

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.
Three topologies of ethernet connection to the router are available:
• Ring configuration
