I am laying out the installation of a Orion-TR Smart 12/12-30 Isolated as a charger and found a diagram in the installation instructions. The alternator positive is shown being moved off the Battery with a fuse added and the run between the Alternator and the Orion-TR Charger is unfused. Is this correct?
Can I add a breaker/fuse in the run from the battery to the charger, leaving the alternator battery as originally installed?
It is always best fuse on the incoming and outgoing as close as you can to the batteries. Cable shorts against the body can explode batteries. If you cut off current sources at the source then there is nothing to sustain fires as well.
The picture shown in the manual is pretty good practice. Also always use the recommended sizes.
My concern is the direct run from the alternator to the Orion-TR. It appears that the Orion is not protected from issues with the Alternator nor the Alternator with issues with the cabling and or the Orion-TR. If I leave the Alternator connected to the Battery and fuse the cable connection running to the Orion I think I will be protecting all three from each other.
Alternator 130A, Fuse 60A, cabling 6awg, Orion-TR dc/dc 12 to 12 30A
