Shore Power:
The motorhome is equipped with a shore
power cord to connect the motorhome to
outside electrical services. Shore power
service is the most efficient source of electrical
power. The plug end of the shore power cord
is 50 Amp120/ 240 Volt AC. When this type
of power source is not available, electrical
adapters will be required to allow a proper and
safe connection to the electrical service supply.
NOTE
When 50 Amp shore service is not
available, care will have to be used
when operating the appliances and
using the outlets to avoid overloading
the shore power service.
Generator:
The generator can be selected for use when
shore power is unavailable. The maximum
amount of generator output power, measured
in watts, is calculated at an elevation of 500’
above sea level. This figure decreases slightly
at higher altitude. Ambient temperature also
effects total maximum output. The amount
of AC electrical load applied to the generator
determines fuel consumption.
Inverter:
The inverter is an auxiliary 120 Volt AC
power source that inverts 12 Volt DC house
battery power to 120 Volts AC. This device
has limited AC power output, measured in
watts, and operates only selected appliances
and outlets. The inverter also converts 120
Volts AC power, supplied from either shore
power or the generator, to 12 Volts DC power,
to recharge the batteries. When dry camping,
the inverter may be used to supply power to
selected outlets.
BATTERY DIScONNEcT
House
The house battery
disconnect switch turns the
house battery power supply
on or off by disconnecting
12 Volt DC power to the
following items: inverter,
house fuse panel above the
driver, house fuse panel in
the roadside front electrical
panel. Turn the house battery
disconnect switch off when
the motorhome is going to
be stored for more than 48
hours or before performing
electrical maintenance. If possible, leave the
motorhome plugged into an outside electrical
service with the house battery disconnect
switch on to help prevent the possibility
of dead batteries. Use of the house battery
disconnect switch will not turn off all DC
electrical items or other parasitic loads present
on the house battery.
BATTERY cUTOUT SWITcH
The battery cutout switch is
located inside and next to the
entry door. This switch controls
the 12 Volt DC power to the house fuse
panels.
When the switch is activated, power is
supplied to all the interior DC lighting and DC
operated appliances. Some appliances require
both DC and AC power to operate, such as
the roof air conditioner. This switch is helpful
when dry camping to conserve house battery
power. Refrigerator and inverter operation
are unaffected by the operation of this switch.
When turned off, this switch will not stop all
parasitic loads and therefore is not a substitute
for the house battery disconnect switch.
CAUTION
To avoid flash damage to electrical
contacts, turn off the interior lighting
before activating the battery cut-off
switch.
SHORE pOWER
HOOk-Up
The power
requirement for the
motorhome is 50
Amp 120/240 Volt
AC single phase.
The motorhome
can be operated
from 30 Amp
120 Volt AC
but with limited
capacity. If 50 Amp shore power service is
available, connect the supplied shore power
cord. If less than 50 Amp service is available,
electrical adapters will be required and power
consumption must be reduced to avoid tripping
the shore power breaker. The shore cord is
stored in a roadside compartment.
CAUTION
Avoid flash damage to the electrical
system contacts. Before plugging the
motorhome into shore power, starting
the generator or using the inverter
make sure all the appliances are off.
Located in curbside
battery compartment.
