Power Bright APS300 - Manual (Page 6)

-Lay the flexible chassis ground cable from the chassis of the
vehicle to the chassis ground on the rack of the inverter.
-Connect the chassis ground.
! Reverse polarity connection of the battery wires can damage
the inverter. Do not use the inverter with electrical systems
using positive ground.
Operation: 300 Watt Pure Sine Wave Inverter
Power on
On the LED control “Power” lighting - Green LED.
Over load
One the LED control “Over-Load” lighting-Red LED.
Over temperature
On the LED control “Over-Temp” lighting-Red LED.
Problem Possible Cause
No output voltage,
LED does not light 1. On/Off switch is not in the power ON
position.
2. Bad contact of the connections
between battery and inverter.
3. Internal fuses blown. In this case,
send the unit back to Power Bright for
repair.
No output voltage, OVER-TEMP
LED Lights Red The inverter has been overheated.
Switch off the inverter and the device.
Wait approx. 2 minutes and switch on
the inverter only. Reduce the load and
make sure that there is better
ventilation for the inverter. Then switch
on the inverter and the device again.
Overload LED Current consumption of the device is
too high. Also there could be a short of
the device. Switch off the inverter and
disconnect the device. Switch on the
inverter again. If the OVERLOAD LED
is off, there is a short circuit in the
device or the total load was higher
than the specified wattage of the
inverter. Check the connecting cable of
the consumer for mechanical
damages.
Audible signal in case of under
voltage Battery voltage too low. In case of the
battery load voltage falls below 11V
resp. 22V. The battery has to be re-
charged.
