What is the make of your load center where all the fuses and breaker are located?
Not that one............the one inside where the cabin fuses and service breakers are found. Dark brown cover usually. Near the floor level.
It should be close to that as they don't like to put them far away from the breakers............but, does this unit have an inverter/charger? IF SO, it won't have a converter.
Then I will opt out of this question and let another tech offer something if they can. We don't have any diagrams of these and have to hunt for them ourselves in the shop. Sorry I couldn't be more help here.
