How do I connect a PVD-150-31RS (www.allelectronics.com) I can not find schematic anywhere?

I want to use this to regulate my variable volt ( 150+ volts DC) pedal power unit. This Martek power Inc. regulator is perfect and cheap. I don't want to do it by gut feelings, destroy it or even harm myself. I have build several 12 volt regulators but current supply ( 12+ Amps, expensive to build) is my mean concern.
