The REACT2 system is equipped with a BACKUP AC output that can
be activated in two different ways (Auto or via external control) settable
In case of external control (BKP terminals) selection, backup output is
activated when terminal 1 is brought to the same potential as terminal
3 (i.e. positioning a switch to create a short circuit between the two
terminals on the communication and control signal terminal block
The condition of going into backup is shown on the synoptic.
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
block).
The connection and disconnection of the inverter to and from the grid can
chapter 7).
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 REM
terminals (terminal 2 and terminal 4) on the communication and control
signal terminal block
.

When terminal 2 is brought to the same potential as terminal 4 (i.e.
positioning a switch to create a short circuit between the two terminals),
the inverter is disconnected from the grid.
The connection and disconnection of the inverter to and from the grid can
be controlled through an external control.
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
block).
