Noob Question: Hooking up 2 positive Linear power supplies for +- output?

[hifimaker]

I have 2 linear bench power supplies 0-30VDC at 5amps set to output 15VDC each.

I'd like to hook them up so I get Plus and Minus voltage, +-15vdc.

How would I wire them together?

PS1 gnd to PS2 +?

Thanks!

I figured it out. The hook-up worked, got +- 15VDC.
