3.6 Power Routing in the Display
Following is a basic overview of power routing. Check exact power routing for a specific
display on the Layout Drawing found in Appendix A.
A general power routing, as shown in Figure 25, can be summarized as follows.
1.
Power terminates internally to the power termination panel.
2.
Power travels through the transformer which adjusts power to the appropriate voltage
for the controller.
3. Power is routed through filters to the power supplies which provide power to the
modules.
4.
Power is also sent from the last breaker on the power termination panel through a filter
to the fans and the thermostat.
Note: Power supplies are preset to the proper voltage: 12-13.1VDC.
