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 2–7).
3. Restart your appliances while in shore power mode.
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:
u Turn 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.
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.
