Battery Disconnect - House; Battery Cut-Off - Holiday Rambler Imperial 2008 Owner's Manual

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 effi cient source of electrical power. The
plug end of the shore power cord is 50 Amp,
240 Volt AC. When this type of power service
is not available, electrical adapters are 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. Maximum amount
of generator output power, measured in watts, is
calculated at an elevation of 500 ft. above sea level.
This fi 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:
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 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, domestic fuse panel in the front
electrical bay and domestic power supply in the
rear run box. 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 battery disconnect
switch on to help prevent the possibility of dead
batteries. Use of this battery disconnect switch
will not turn off all DC electrical items or other
parasitic loads present on the house battery.
Some are federal mandate items such as the
LP-Gas detector.
NOTE:
The solar panel (optional) will charge the
batteries with the disconnect switches 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.
When the switch is activated, power is
supplied to all interior DC lighting and DC
operated appliances. 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.
