nope. just have them share the same ground (or earth ground.) use diodes if youre worried about one feeding in to the other.

So, if they are different types of PSUs (e.g: one is an 12v SLA and the other is a rectified toroid), do you just have to connect their grounds together?

oh one's a battery? since your transformer is a toroid, couldn't you just throw a low voltage winding onto it?

It'd be a bit off a mess with extra rectification and smoothing and also I tend to be a perfectionist sometimes.

I'll repeat the question: So I can connect both of the grounds together even if they are different types of PSUs?
