The inverter/converter can be used for silent AC power if shore power is
not available, and using the generator is not going to be selected as a secondary
power source option. This device has limited AC power output, measured in
watts. It operates only selected appliances and outlets. The inverter/converter is
two components in one. Its first function is as an auxiliary 120 Volt AC power
source that uses 12 Volt DC house battery power to invert to 120 Volts AC. The
second function of the inverter/converter is to use 120 Volts AC power, supplied
from either shore power or the generator, and convert it to 12 Volts DC power
to recharge the batteries.
The main battery disconnects are located
in the rear passenger side battery compart-
ment. In the compartment are a pair of bat-
tery disconnects: One for the chassis batter-
ies and the other for the house batteries.
Turn off the batteries anytime the
motorhome is going to be stored and not in
use. If possible, leave the motorhome
plugged into an AC source with the battery
disconnects on. This will help prevent the
batteries from going dead. Use of the battery
cut-off switch at the entry door will not turn
off all DC electrical items. There are small
“parasitic” loads that are present on both the
house and chassis batteries. Some are federal
mandate items, such as the LP detector. If
the motorhome will not be used, or will be
stored for more than 48 hours, it is recom-
mended to turn the batteries off.
The battery cut-off switch is located inside and next to the entry door. This
switch controls the 12 Volt DC power to the domestic fuse panels. When the
switch is ON 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 and
can be used to conserve house battery power. Refrigerator and inverter opera-
tion 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 main bat-
tery disconnect switch.
