The right way to connect DC terminals

Nabiru3Nabiru3 Posts: 13Registered Users ✭✭
So in the back of my inverter (in the DC terminals section) I have a cable lug, nut, washer and a washer lock. And I have no idea how to put them in the right order. Should the cable lug be connected directly to the terminal end of the inverter ? or should I put the washer and its locker between the cable lug and the terminal end ? Please help 😥.

*attached is an image of my situation, I placed them in the order I think it's most appropriate but didnt tighten them up.

    IMHO, the lug probably goes on first, then the washer (to spread load over more of the lug), then lock washer, and nut last.
