11.2 Connections to the
communication and control board
The communication
connected to the communication and control board
(26) inside the wiring box. To reach the board, on
the right side of the wiring box, there are:
• 2x PG16 cable glands (cable range accepted 10-
14mm) (13)
• 2x PG21 cable glands (cable range accepted 13-
18mm) (13)
D NOTE –
As an alternative, the standard
gasket of the PG21 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.
A ATTENTION –
Please
unused cable glands (13) are properly sealed
by the IP65 plastic cap (pre-installed on cable
glands).
Check the tightness of the signal cable glands (13)
(5 Nm PG16 cable gland / 7.5 Nm PG21 cable gland)
at the end of wiring operations.

11.3 Ethernet connection

The connection of the ethernet communication
cable must be made on the specific connectors (44)
are
(45) located on the Communication and control
board (26). 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 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
• 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.

A ATTENTION –
and/or in presence of adverse weather/strong
electromagnetic events it is advisable to use
additional overvoltage protective devices.
Three topologies of ethernet connection to the
router are available: Ring configuration, Daisy chain
configuration, star configuration.
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.
