On the Digitrax Super Empire Builder system you will find a white connector with seven (7)
screw terminals. Each of the screw terminals are labeled on the
system.
Make sure your power supply is NOT
plugged in.
If you have a Digitrax Chief or Super Empire Builder you will attach
the two wires from the power supply to the terminals marked "Power
In". It doesn't make any difference which wire goes into the
terminals because your power supply is "Alternating Current" A.C.
Now tighten down the screws to hold the wires in place.
