Start-up

ON/OFF Switch - Turning the inverter ON and OFF is controlled by a
momentary switch on the front of the inverter (see figure 2, item 2).
When the inverter is connected to the batteries, or when its automatic
protection circuit has turned the inverter off, the ON/OFF switch will need
to be pressed to start the unit. Once the inverter has been turned on,
pressing the ON/OFF switch alternately turns the unit on and off.
Note: The ON/OFF control switch is a small momentary switch
which functions by lightly pressing and releasing.
Status Indicator - The status indicator is a green LED (Light Emitting
Diode) that provides information on the operational mode of the
inverter. Watch the status indicator (see figure 2, item 1) for at least 10
seconds to verify or determine the inverter's operational condition
from the information below.

Normal Operation

• Off - The inverter is off.
shore or generator at the inverter's output terminals.
• On (solid) - The inverter is in Transfer Mode. The external AC
power (utility power or generator) connected to the inverters input
is passing to the inverters output to power the AC loads.
• Blinks on once every second - The inverter is on and using
energy from the battery. The inverter is either 1. Providing full
power to the loads connected to the inverter; or 2. In Search Mode,
ready to supply AC power to the loads connected to the inverter.
Protection Mode
There are five fault conditions that will cause the inverter to
shutdown; Low Battery, High Battery, Over-temperature, AC
Overload, and Internal faults. If your inverter has shutdown,
monitor the status indicator and count the number of blinks that
occur every four seconds to determine the particular reason for
the shutdown. Once you have determined the reason for the
shutdown, refer to the Troubleshooting section to help diagnose/
clear the fault condition.
• Blinks on 1 time every four seconds - Low Battery fault.
• Blinks on 2 times every four seconds - High Battery fault.
• Blinks on 3 times every four seconds - Over-temperature fault.
• Blinks on 4 times every four seconds - AC Overload fault.
• Blinks on 5 times every four seconds - Internal fault.
Charge Mode
Some units are equipped with the internal battery charger, with this
option the green LED status indicator provides additional informa-
tion:
• Blinks off every four seconds - The unit is charging the batteries
connected to the inverter.
