Am installing a contactor on a large battery project with an Orion BMS and was wandering if:
1. Is there a preference of having the contactor load side control the connection/disconnection of the positive over the negative or vice versa?
2. The marked A1 and A2 main contacts are marked with positive and negative...
What does it mean? it can't be positive and negative as the main contacts control the connection/disconnection of a single wire so it's either the positive OR the negative.
3. The battery side I'm assuming connects to the A1 and the controlled side to A2 right?
Many say it doesn't matter as it's just a switch but I read that in certain contactors there are arc chutes and/or other mechanisms that do have an importance to which way the current flows.
