Inverter Startup; Table 3-1, Inverter Battery Turn On/Off Levels - Magnum Energy MMS Series Owner's Manual

Operation
• Internal Fault – The inverter continually monitors several
internal 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 again.

Inverter Startup

ON/OFF Switch – The MMS Series 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 determine
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.
