1.2.2 Power ON/OFF Button
The Power ON/OFF button is located in the left of the panel. Press to power the Inverter/Charger ON or OFF. When the button is
pressed, the alarm will beep.
Note: When connected to batteries, the Inverter/Charger will start up even if not connected to AC power. Defaults to 60Hz.
Note: Unit is in BYPASS mode as soon as power is applied to the input.
Power On:
Press the Power ON/OFF button for 3 seconds until the alarm beeps and the INVERTER MODE light illuminates.
Power Off:
Press the Power ON/OFF button for 3 seconds. The alarm will beep when the shutdown process is completed.
1.2.3 DC Mode Inverter (LED 1)
This LED illuminates to indicate that the system is working in inverter mode (supplying power from battery).
1.2.4 AC Mode Charger (LED 2)
The LED flashes during the charging process and remains illuminated once the battery is full charged.
1.2.5 Inverter Condition (LED 3)
When the inverter temperature exceeds the default setting, this LED will flash and the inverter will shut down automatically.
After the temperature returns to normal, depress the Power ON/OFF button to restart.
When the unit is overloaded in DC mode, LEDs 1, 3 and the audible alarm indicate inverter status as follows:

Battery High:
In AC mode, LED 4 will flash.

LED 4 will illuminate and the alarm will beep once every five seconds for three minutes. If the battery voltage
drops below the cutoff voltage (LBCO), then the inverter will shut down all LEDs except LED4, and will turn off.
