– The inverter continually monitors several inter-

nal components and the processor communications. If a condition
occurs that doesn’t allow proper internal operation, the inverter
will shut down to protect itself and the connected loads. The
inverter will need to be reset to start operating.

Startup

ON/OFF Switch – The inverter can be turned on and off by lightly
pressing and releasing the Power ON/OFF switch on the front of the
inverter. When the inverter is fi rst 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 Power ON/OFF switch alternately
turns the inverter on and off.

WARNING: The Power ON/OFF control switch does not
turn on or off the charger feature. If AC power (utility or
generator) is connected and qualifi ed on the AC input,
this AC power will also be available on the AC output and
is not controlled by the Power ON/OFF switch.

Status LED Indicator – The status indicator is a green LED (Light
Emitting Diode) that provides information on the operational mode
of the inverter. Watch this indicator for at least 10 seconds to deter-
mine the inverter’s operational condition from the information below:
Inverter Mode

Off – Indicates the inverter is off; there is no AC power from
the inverter, shorepower, or generator at the inverter’s output
terminals.
Blinks On (once every second) – The inverter is on and is using
energy from the battery. The inverter is either providing full power
to the loads connected to the inverter, or it’s in Search mode and
ready to supply AC power to the connected loads.
