OPERATION
The Freedom 458 Inverter/Charger provides
120 volt AC power from auxiliary DC batteries,
automatic battery charging and automatic AC
transfer switching between an external AC
source and inverter mode.
External AC Power
When external AC power is available, the
three-stage battery charger, transfer switching,
and Power Sharing automatically function.
When external AC power is not available
and the INVERT switch is ON (either through
the auxiliary switch or the INVERT button on
the remote), the inverter will automatically turn
ON. If the INVERT switch is OFF (the INVERT
LED will not be illuminated), the inverter will be
OFF.
If installed with the Remote Control Panel
or Link Instrumentation, the unit will be set up
and controlled from the remote. Refer to the
remote manual for more information.

pressing this switch will turn the charger OFF.
• Select the battery type
After holding the INVERT switch for five seconds,
press the CHARGE switch to select the battery
type. One of the four LEDs will rapidly blink,
indicating the present battery type setting.
Press the CHARGE switch again to change
the battery type. Continue to press until the
desired battery type is selected. If the CHARGE
switch is not pressed for five seconds, the unit
will return to normal operation and the battery
type selection will have been made.
When the 12-volt input to the unit is
