Power Supplies

The power supplies convert standard 110 or 230 VAC to DC voltages for the various switch circuits. Each power supply has an AC power receptacle, an On/Off switch, and two status LEDs as shown in Figure 2-9. After connecting a power supply to an AC voltage source and placing the power switch in the On position, the power supply is energized and DC voltage is delivered to the switch logic circuitry. Refer to Section 6 Removal/Replacement for information about replacing a power supply.
