"L H remote" for Orion 48 to 12 DC converter (30 amp model)?

Couple questions:

a) can this “remote” slot be used to power the Orion on and off via the Cerbo relay?

b) how do I connect the negative and positive cables to this remote slot? Do I need to buy some kind of plastic component?

Many thanks. I have a 48 to 48 Orion and the wire just wired up into it, but this one is different and I’m not sure what I need to make it work remotely.

Thanks. Not sure if I lost that or what. Any idea if that is that something I need to get from Victron or is it more standard than that?

For others looking, it’s a phoenix connector, 5.08mm pitch. https://www.amazon.com/kuosbiu-Pluggable-Terminal-Phoenix-24-12AWG/
