Park Fuses or Breakers
Most campgrounds are equipped with a fuse
or circuit breaker at the receptacle. This protects
the park’s wiring, as well as the power cord on
your vehicle, from electrical damage. If electrical
power fails, contact the park attendants and have
them check the fuse or breaker for your supply
receptacle.
After disconnecting the power cord, neatly re-
place it in the storage compartment.
POWERLINE ENERGY MANAGE-
MENT SYSTEM (EMS)
The energy management system (EMS) mon-
itors the electrical usage of the appliances and
equipment in the coach and distributes the elec-
trical loads to avoid nuisance tripping of the
shoreline circuit breaker. This system works
together with the energy efficient central air con-
ditioner to allow you to run both compressor
units at the same time on a 30-amp shoreline
connection.
Please read your PowerLine Energy Manage-
ment System Owner Guide for important infor-
mation on running both air conditioner
compressor units at the same time. This guide
will also explain how this system operates under
several conditions, whether 20-amp, 30-amp or
50-amp connections.
POWER CONVERTER
SYSTEM
The power converter changes 110-volt AC
current from the auxiliary generator or the shore-
line into 12-volt DC current for use by 12-volt
equipment 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.

Inverter Control Panel:
The inverter/charg-
er also has a remote monitor/control panel
that can be programmed for several charging
configurations.
See the inverter/charger remote panel instruc-
tions in your Owner InfoCase for complete
Do not
plug the power cord into an
outlet which is not grounded, or adapt
the plug to connect to a receptacle for
which it is not designed.
Be sure that all four prongs of the sup-
ply cord are properly plugged into the
receptacle.
Do not
connect the power cord to an
extension cord.
