ELECTRICAL SYSTEMS
Charging Section
The converter charges the coach battery while
110-volt external power is connected. The con-
verter will automatically “sense” the condition of
the coach battery. If it is below “full charge”, the
Charging Section will start charging the battery.
If the coach battery has been extremely dis-
charged, it will accept charge at a relatively high
amperage rate. If battery is only slightly dis-
charged, it will charge at a lower amperage rate.
The rate of charge will decrease as the battery
reaches “full charge”, then will remain “trickle”
charging at a very low amperage rate. If your
storage battery does not charge as described
above, it is possible the battery is defective.
NOTE: We do not recommend leaving the shore-
line plugged in continuously during stor-
age periods because the batteries can
lose electrolytic fluids and become dam-
aged from continuous charging without
periodic use. We recommend following
regular battery inspection and mainte-
nance, especially in cold weather. See
“Battery Maintenance” on page 6-7 this
section.
Thermal Overload Protector
A thermal overload protector will shut-down
the converter if it 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: 12-volt lights and motors will automati-
cally draw from battery power in this
event.
The thermal overload protector will reset itself
after a cool-down period, and the lights and mo-
tors will again resume operation from the con-
verter. If the overload trips again shortly after
reset, take immediate steps to correct cause of
overheating. A portion of RV 12-volt load (lights
or motors or both) should be turned off to reduce
total load. Also, inspect power converter section
to make certain ventilation is not blocked.
NOTE: The converter will not change 12-volt
DC current to 110-volt AC.
110-Volt Circuit Breakers
The breaker panel protects all 110-volt com-
ponents in the motor home from either an over-
load on the circuit or a short in the wiring or
component itself. When an overload or short de-
velops, the breaker will open preventing any fur-
ther flow of electricity and, therefore, damage to
the system.
Shut off the equipment (example: roof air con-
ditioner) and allow a brief cooling period. Then
reset the breaker by moving the switch to “Off”
and back to “On”. If the breaker is continually
tripped and no overload is evident, have the sys-
tem checked for a short in the wiring or the appli-
ances.

WARNING
Do not store anything around or on
top of the converter, or in front of the
cover. The converter generates heat
while operating, and needs unre-
stricted air flow for proper cooling.
