Recovering from Low Battery Voltage Shutdown
If the Low Battery light illuminates and the Inverter ON light turns off on the front panel when you are operating the unit, the RS400 has shut down due to low battery voltage (10.3 volts). Output power is interrupted.
To recover from a low battery voltage shutdown:
1.Turn off your appliances.
2.Connect the unit to an AC source to switch to shore power mode (see “Operating in Shore Power Mode” on page
3.Restart your appliances while in shore power mode.
Note: If you want to switch to inverter mode right after a low battery voltage shutdown, you have to start recharging the battery with a separate charger even in shore power mode. The moment you do step 2, the unit automatically resets the low battery voltage shutdown. So if you start recharging the battery and shore power is suddenly disconnected, the unit can still operate in inverter mode until a low battery voltage condition occurs again.
Restarting or Operating Multiple Appliances
The RS400 can handle several appliances simultaneously as long as they do not draw more than 400 watts in total.
To restart or operate several appliances:
uTurn each appliance on separately after the RS400 has started.
This action ensures that the RS400 does not have to deliver the starting current for all the loads at once and will help to prevent an overload shutdown.
