How to wire MRC power station 8 to Digitrax Empire Builder

[HELP! I have an Empire Builder stater set and a DT400 throttle. I recently aquired 3 MRC Power Station 8’s. How do I wire them up with my Digitrax command station. I want each one to power a seperate block. Do I wire my UP5’s as usual? In other words do the MRC’s effect the LOCO-Net wiring. I appreciate any help. Stan
