Orion DC DC fuse wire diagram

Hi, I’m just about to connect my Orion DCDC charger and have 2 x 60 amp breakers to install inline as the “external battery protection fuses” I want to know 1. If I install the fuse inline from Alternator to start battery, Then would I need to also have one inline from start battery to DC DC charger input? Additionally I will install another 60amp breaker inline from DCDC charger output to House bank. You direction assistance here is appreciated.

From the manual. One on the input, one on the output as close as possible to the current sources (batteries)

Picture here.

Thanks Alexandra. I have seen the manual and photo but it only indicates the fuse attached directly to the battery itself. As I will run all new cable directly from alternator to the start battery then to the DC DC charger I’m still not certain exact location of the fuse. will it be inline before the battery (inline on the alternator side) or after the battery (between battery and DC DC charger input? Thanks

There is no fuse between the alternator and the start battery. It is just the DC-DC converter that is fused (in and out).
