Isolated DC-DC Converter and MOSFET Driver Connection

Hi,

I'm designing an active rectifier made up from 4 SiC MOSFETs (2 Upper and 2 Lower),
After a Market survey I decided to use an isolated MGJ6D242005DC DC-DC Converter and an 1EDC60H12AH MOSFET Driver.
I don't understan how to connect them correctly.

1EDC60H12AH

As you can see from the datasheet PIN CONNECTION of MGJ6D242005DC there are
pin4 5VB RTN
pin5 5VA RTN/5VB
pin6 24V RTN/5VA

What are them?

Thank You.
