Mount enclosure in secure location near an AC power outlet that is not controlled by a switch. (supplied power cord is 6 feet long) 3. Connect devices to be powered to the screw terminals for DC output. The power distribution board has three sets of outputs, each set is limited to 2. 5 amps. If a device requires more that 2. 5 Amps, parallel two sets of terminals. Warning High Voltage is now present at the power supply AC input terminals. The LEDs at the power outputs should be on (if any are off, check for overloaded condition). If AC power is lost, the Low Battery circuit will disconnect the battery if it's voltage drops below 10 Vdc. This helps to prevent "deep discharging" of the battery.
