52 Freedom X Owner’s Guide
Operating During Transition Between AC Mode and Battery Mode
Overload Conditions
There are two kinds of overload conditions:
• an overload warning
• an overload shutdown
Overload Warning When the Freedom X’s AC load is
approximately 100 W below the overload shutdown limit of
~1200
W, the audible alarm beeps once every two seconds and the
LCD screen shows a fault code .
Overload Shutdown When the Freedom X’s AC load increases
to near ~1300 W, the audible alarm beeps every second and the
LCD screen shows a fault code . The Status LED turns solid
RED and in 30 seconds, both the unit and the LCD screen will shut
down to prevent damage to the inverter and protect the battery from
being over-discharged.
High Surge Loads
Some induction motors used in freezers, pumps, and other motor-
operated equipment require high surge currents to start. The
Freedom X may not be able to start some of these motors even
though their rated steady state current draw is within the inverter’s
limits. The unit will shut down and indicate an overload shutdown.
Over-temperature Conditions
During inverter operation, when the Freedom X’s internal
temperature starts to approach its preset shutdown limit, the alarm
will beep every two seconds and the display will show fault code
. If the over-temperature condition persists, the alarm will beep
once per second and the display will show fault code . The
Status LED turns solid RED and the inverter will shut down to
prevent damage to the inverter and protect the battery from being
over-discharged. However, when the internal temperature drops and
falls within normal operating temperature, the Freedom X will
recover automatically and will continue inverting.
Routine Maintenance
Freedom X Unit
Minimal maintenance is required to keep your Freedom X operating
properly. Periodically you should:
• Clean the exterior of the unit with a damp cloth to prevent the
accumulation of dust and dirt.
• Ensure that the DC cables are secure and fasteners are tight.
• Make sure the ventilation openings are not clogged.
