Operating During Transition Between Shore Power and Inverter Mode

High Surge Loads
Some induction motors used in freezers, pumps, and other motor-
operated equipment require high surge currents to start. The
Freedom HF 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 mode, when the Freedom HF’s internal
temperature starts to approach its preset shutdown limit, the
alarm will beep every two seconds and the display will show fault
code
E07
. If the over-temperature condition persists, the alarm will
beep once per second and the display will show fault code
E04
.
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 HF
will recover automatically and will continue inverting.
During AC shore power mode, when the Freedom HF’s charger
temperature starts to approach its limit, the charging current will
be reduced to 10 amps (Freedom HF 1000 models) or 20 amps
(Freedom HF 1500/1800 models).
The Freedom HF also monitors the internal transfer relay
temperature. It automatically turns on the fan when the relay
starts to approach its preset temperature limit and turns off when it
cools down. If the relay exceeds its preset temperature limit, the
display shows a fault code
E11
