NOTE:
When 50 Amp shore service is not
available, take care 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 ft.
above sea level. This gure will decrease 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/Charger:
The Inverter/Charger 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/Charger 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/Charger may be used to supply power
to selected outlets.
BATTERY DISCONNECT - HOUSE
The main house battery disconnect switch
turns the house battery power supply on or
off by disconnecting 12 Volt DC power to the
following items: inverter, domestic fuse panel
in the bedroom, and the fuse panel in the front
electrical bay. The switch is located in the rear
curbside bay. 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 outside
electrical service with the battery disconnect
switch on to help prevent the possibility of dead
batteries. This switch does not turn off all DC
electrical items or other parasitic loads present
on the house battery.
NOTE:
The optional solar panel will charge
the house batteries with the disconnect
switch off.
BATTERY CUT-OFF
The battery cut-off switch is
located inside the motorhome
next to the entry door. This
switch controls the 12 Volt DC
power to the domestic fuse
panel and Multiplex System.
Power is supplied to all interior
DC lighting and DC operated
appliances when the switch
is activated. Some appliances
will 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 use of this switch. When
the interior house power is off there are still
parasitic loads on the house batteries; therefore,
it is not a substitute for the main battery
disconnect switch.
CAUTION:
Avoid flash damage to electrical
contacts. Turn off the interior lighting
before operating the battery cut-off
switch.
Located in the rear curbside
compartment.
