3.6 Power Routing in the Display
Following is a basic overview of power routing. Check exact power routing on Drawing B-
277048 found in Appendix A.
A general power routing, as shown in Figure 22, 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
MLC and modules.
4. Power is also sent from the last breaker on the power termination panel through a
filter to the thermostat and fans.
Note: Power supplies are preset to the proper voltage: 9 VDC.
