Multifunction Relay connection (ALARM and AUX)
The inverter is equipped with 2 multifunction relays terminal blocks
(33)
with con-
figurable activation. It can be connected with normally open contact (being con-
nected between the NO terminal and the common contact C) and with normally
closed contact (being connected between the NC terminal and the common con-
tact 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, pro-
vided they comply with the following requirements:
Alarm terminal block requirements
Alternating current
Maximum Voltage: 160 Vac / Maximum Current: 6 A
Direct current
Maximum Voltage: 30 Vdc / Maximum Current: 3 A
Cable requirements
Conductor cross-section: from 0.08 to 1.3 mm²
For further information regarding the configuration and use of the mul-
tifunction relay terminal blocks, please refer to the user manual.

Remote control connection
The connection and disconnection of the inverter to and from the grid can be con-
trolled 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
(38)
terminal block of the communication and control board
(28)
.
When the R2 signal is brought to the same potential as the RTN signal (i.e. by mak-
ing a short circuit between the two terminals of the connector), this causes the in-
verter 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 pass-
ing 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).
For further information regarding the configuration and use of the Re-
mote control terminal block, please refer to the user manual.
