The connection and disconnection of the inverter to and from the grid can
be controlled through an external control.
The function must be enabled in the relevant menu through the Aurora
Manager Tools software. If the remote control function is disabled, the
switching on of the inverter is dictated by the presence of the normal
parameters which allow the inverter to connect to the grid.
If the remote control function is operating, besides being dictated by the
presence of the normal parameters that allow the inverter to connect to the
grid, the switching on of the inverter also depends on the state of the R1
ON/OFF and R2 ON/OFF terminals compared to the RTN terminal present
on the a11 connector of the communication and control board
When one of the R1 ON/OFF or R2 ON/OFF signals is brought to the
same potential as the RTN signal (i.e. by making a short circuit between
R 1
O N
/ O
the two terminals of the connector), this causes the inverter to disconnect
O N
F F
/ O
F F
from the grid.
The connections of these controls are made between the "R1 ON/OFF"
and the "R1 ON/OFF" inputs compared to the common "RTN" signal.
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 inverter is equipped with 2 multifunction relays 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).
Different types of devices (light, sound, etc.) can be connected to the
relay, provided they comply with the following requirements:
Alternating current
Maximum Voltage: 240 V AC
Direct current
Maximum Voltage: 30 V DC
Cable requirements
External diameter: from 5 to 17 mm
Conductor cross-section: from 0.14 to 1.5 mm
This contact can be used in different operating configurations that can be
selected by accessing the embedded web server.
