Which side of cutoff switch to connect charge controller?

I'm curious as to which way others are going when hooking up their charge controller. Are you connecting it to the battery side or the load side of your disconnect switch (assuming you have one). ...

on the batteries
you want the controller charging the batteries, keeping them charged, protected from self discharge et..
and
you risk killing the controller, IF you put it on the load side
all controllers say connect to batteries first, then connect controller

when working on system disconnect the panels FIRST then the batteries
never have panels connected UNLESS there is a good battery already connected
