Determine cable cross-section
The minimum cable cross-section depends on the maximum cable length:
9.1 Connect charging converter
Connect the charging converter as shown:
– Correct connection diagram: fig. , page 5
– Connecting the batteries: fig. , page 6
– Connect control line (I1): fig. , page 6
9.2 Connect accessories
Connect the accessory to the following contacts:
– Performance regulation (I2): fig. 5, page 3
– Temperature sensor: fig. 6, page 3
NOTE
Keep the distance to the body battery as short as possible.

NOTICE!
The charging converter must not be connected directly to the alternator.
NOTE - Performance regulation
To limit the output current of the charging converter to 5 A, a positive
control signal must be present at contact “I2” (fig. 5, page 3).
