High Surge Loads
Some induction motors used in freezers, pumps, and other motor-
operated equipment require high surge currents to start. The
Freedom EX 4000 may not be able to start some of these motors
even though their rated steady state current draw is within the
inverter/charger/converter’s limits. The unit will shut down and
indicate an overload shutdown.
Over-temperature Conditions
During inverter operation, when the Freedom EX 4000’s internal
temperature starts to approach its preset shutdown limit, if
installed, the display on the Freedom EX Remote Panel (PN: 808-
0817-03) will show error code
E07
. The Event LED will flash.
If the over-temperature condition persists, if installed, the display
on the Freedom EX Remote Panel (PN: 808-0817-03) will show
error code
E04
. The Event LED will turn on and the
inverter/charger/converter will shut down to prevent damage to the
inverter/charger/converter and protect the battery from being over-
discharged.
