Please read your PowerLine Energy Manage-
ment System Owner's Guide for important infor-
mation on running both front and rear roof air
conditioner units at the same time. This guide
will also explain how this system operates under
several conditions, whether 20-amp or 30-amp
connections.
POWER CENTER (Converter)
The power center changes 110-volt AC cur-
rent from the auxiliary generator or the shoreline
into 12-volt DC current for use by 12-volt equip-
ment in the motor home.
Certain circuits, however, remain unchanged
for use by items which require 110-volt current,
such as the air conditioner(s), the refrigerator in
AC mode, the microwave oven, etc.
Current drawn from the coach batteries passes
through the power center unchanged, although it
is routed through a series of protective circuit
breakers.
The converter is located in a lower cabinet in
the galley, living area.
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.
Charging Section
The converter charges coach batteries while
110-volt external power is connected. The con-
verter will automatically "sense" the condition of
the RV battery. If it is below "full charge", the
Charging Section will start charging the battery.
If the coach 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", the 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.
ELECTRICAL SYSTEMS
Thermal Overload Protector
A protective thermal breaker will "break" the
110-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: Power converter section will automati-
cally route 12-volt lights and motors to
battery power in this event.
The thermal breaker will reset itself after a pe-
riod of time, and the lights and motors will again
resume operation from power converter section.
If the breaker 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
sure ventilation is not obstructed.
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.
