The mains cord has plugs in one side end (On Wall). A male plug (of Power Cord) connects to the mains
outlet on site.
From the Main Circuit Breaker, the AC power is routed via an Inrush Current Limiter to a internal outlet
connector for the Main power supply. The power ON OFF is actually controlled by the MST PWA. This
signal is routed from the Keyboard ON OFF button to the MST board and then to the PDB board.
The MST board has logic that controls the state of this signal. The output from this logic is connected
to the PDB board that either switches on or switches off the Power supply.
