Certain circuits, however, remain unchanged
for use by items which require 120-volt current,
such as the air conditioner(s), the refrigerator in
AC mode, the microwave oven, etc.
NOTE: The converter will not change 12-volt
DC current to 120-volt AC.
Current drawn from the house batteries passes
through the power converter unchanged,
although it is routed through a series of protective
fuses located on the power panel.
Further Information
See the manufacturer’s operation, care, and
maintenance information provided in your
InfoCase.
Charging Section
The converter charges house batteries while
120-volt external power is connected. The
converter will automatically “sense” the
condition of the battery. If it is below “full
charge”, the charging section will start charging
the batteries.
If the house batteries have been extremely
discharged, they will accept charge at a relatively
high amperage rate. If they are only slightly
discharged, they will charge at a lower amperage
rate. The rate of charge will decrease as the
batteries reach “full charge”, then will continue
“trickle” charging at a very low amperage rate. If
your battery does not charge as described above,
it is possible the battery is defective.
Thermal Overload
A thermal overload will “break” the 120-volt
AC power to the converter section of the power
center if the power converter becomes
overheated. This can result from operating above
its maximum limit for an extended period of time
or by obstruction of ventilation to unit.
NOTE: The power converter section will
automatically route 12-volt lights and
motors to house battery power in this
event.
The thermal overload will reset itself after a
period of time, and the lights and motors will
again resume operation from the power converter
section. If the breaker trips again shortly after
reset, take immediate steps to correct the cause of
overheating. A portion of the house 12-volt load
(lights or motors or both) should be turned off to
reduce total load. Also, inspect the power
converter to ensure ventilation is not obstructed.
CIRCUIT BREAKERS – HOUSE
120-VOLT AC
The breaker panel protects all 120-volt
components in the motorhome from either an
overload on the circuit or a short in the wiring or
component itself. When an overload or short
develops, the breaker will open preventing
damage to the system.
Shut off the equipment (example: roof air
conditioner) and allow a brief cooling period.
Then reset the breaker by moving the switch to
“Off” and back to “On”. If the breaker is
NOTICE
Do not block the converter cover vents in
any way. The converter generates heat
while operating and needs unrestricted
airflow for proper cooling. Damage to the
converter can result.
