11.5 Remote control connection
The connection and disconnection of the inverter
to and from the grid can be controlled through an
external control.
The function must be enabled via web server user
interface. If the remote control function is disabled,
the switching on of the inverter is dictated by the
presence of the normal parameters that allow the
inverter to connect to the grid.
If the remote control function is on, besides being
dictated by the presence of the normal parameters
that allow the inverter to connect to the grid,
switching on the inverter also depends on the state
of the R2 terminal compared to the RTN terminal
present on the connector of the terminal block (42)
of the communication and control board (26) .
When the R2 signal is brought to the same potential
as the RTN signal (i.e. by making a short circuit
between the two terminals of the connector), this
causes the inverter to disconnect from the grid.

Since this is a digital input, there are no requirements
to be observed as regards cable cross-section (it
only needs to comply with the sizing requirement
for passing cables through the cable glands and
the terminal connector).
The external switch used for Remote ON/OFF should
be rated for DC low voltage, low current application
(the minimum switching current capability should
be 1mA or lower).

information regarding the configuration and
use of the Remote control terminal block,
please refer to the user manual.
11.6 Multifunction Relay
connection (ALARM and AUX)
The inverter is equipped with 2 multifunction relays
terminal blocks
(41)
with configurable activation.
It can be connected with normally open contact
(being connected between the NO terminal and
the common contact C) and with normally closed
contact (being connected between the NC terminal
and the common contact C). This contact can be
used in different operating configurations that can
be selected by accessing the relevant section in the
web user Interface “SETTINGS > Digital Outputs”.
Different types of devices (light, sound, etc.) can
be connected to the relay, provided they comply
with the following requirements:
