Connect the AC/DC supply
AC/DC models operate on either 120/240 volts, 50/60HZ AC current, or 12/24 volts DC
current.
When using either a converter or a battery charger, make sure that they are connected
in parallel between the battery and the refrigerator. Do not use a converter or battery
charger to supply the DC power directly to the refrigerator because these two devices
do not supply filtered DC power (See Art01521).
