AC input is on / DC output is on. Normal.
AC input is off / DC output is from Battery only . Step
down Transformer is defective or unplugged, or the
AC outlet is off. Battery will eventually discharge.
AC input is on / DC output is off. The auto-reset
overload protector is likely open due to an overload
short circuit. Try reducing some of the device load.

1. Set Master Power Switch (SW1) to Off.
2. 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. (DO NOT
EXCEED 4 AMPS)
4. Connect Battery to the battery wires,
observe polarity.
5. Plug in the AC cord. Warning High
Voltage is now present at the power
supply AC input terminals.
6. Set the Master Power Switch to Power
On. The LEDs at the power outputs
should be on (if any are off, check for
overloaded condition). The connected
devices are now powered.
7. 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.
