Schaudt Elektroblock and Victron Orion 12/30

Hi can i ask a question regarding this please

The wiring between the 4 areas is

1 non isolated orion IN port to engine battery, (nothing into the GND or OUT ports, they remain empty?)

2 ebl 99 rear ports going left to right, nothing in the Rot port and with the Braun and Scwartz ports, (or minus and positive), cable black and red running to the lithium leisure battery.

Would this be correct, are there any other steps required and would you have a simple schematic i could follow please?

Kind Regards declan
