The red wire is allway the plus and the black one allways minus. This new build connection is the so called common ground. It's marked on the boards as COM. The other two are +9V and -9V. One can use them instead of +12V and -12V.

With the Mean Well 15W DKE15A-12 or the Mean Well 15W DKE15A-15 power module one can build an quite powerful power source.
