36 Connecting the Backup Interface

Connecting the Backup Interface

To enable operation of the inverter in the stand-alone mode, the SolarEdge Backup
Interface must be installed. When the inverter switches to the stand-alone mode, the
Backup Interface ensures the neutral conductor continuity to the loads.
For installation and connection instructions of the Backup Interface see:

guide-aus.pdf
When connecting the Backup Interface to the inverter, use the following cable types:
Communication - 0.25 mm
12V power -
If the distance between the inverter and the Backup Interface is smaller than 15
m, use the CAT6 communication cable (see above).
If the distance is greater than 15m/49, use a dedicated cable with a cross section
2
of 2 mm or greater.
To connect the Backup Interface:
1. Connect the communication and 12V power cables to the Backup Interface, as
explained in the installation manual that comes with the Backup interface.
2. Open Communication Gland 1 at the bottom of the Connection Unit.
3. Feed the other end of the communication cable through one of the gland openings.
4. Remove the 7-pin connector from the port labeled Backup Interface on the
communication board.
5. Connect the communication cable wires to the 7-pin connector, as shown below.
For the RSD connection, see Connecting an External RSD Switch (Optional) on page
