Power Supplies and AC Mains Installation
Generally the AC Mains will be connected to either a 2 Amp, 5 Amp or 18Amp 27 volt supply. These
supplies will be either mounted in the upper or lower right hand corner of the cabinet with the
Brigade Board mounted above or below. The wiring should enter the cabinet through the nearest
knockout entry hole on that side. See the following diagrams for the actual wiring and fusing details
for each supply.
