Bornay WIND+ Manual page 49

The connection between the regulator, the master battery and the GX
device (Venus, Colour Control, etc.) must be taught. Failure to make this
connection can result in equipment damage.
As the image shows, from IN2 of the regulator to COM3 of the battery, from NO3 of
the battery to COM of the relay of the GX device, and from NO of the relay of the GX
device to IN1 of the regulator.
The GX device must be programmed as a group start, so that the relay closes and
allows the regulator to operate or opens and stops it. It is recommended to stop
charging at 95% and allow it from 85% of the SOC of the battery.
