Battery Disconnect Switch
The remote battery disconnect switch, located just
inside the entry door, is used to separate the 12-volt
distribution panel from the converter charging system�
When connected to an external AC power source, the
12-volt distribution panel will receive power from the
converter and the touring coach will function normally�
The batteries will be charged through the converter
charging system regardless of if the battery disconnect
switch is in the ON/OFF position�
If the touring coach is NOT plugged into an external
AC power source and the switch is turned to OFF the
batteries are disconnected and the 12-volt distribution
panel will not receive power from the converter� The
OFF position is intended for storage of the touring
coach or when power conservation is desired�
The solar panels will charge the batteries regardless of
the battery disconnect switch position� Likewise, if ON
or OFF, the generator will charge the batteries when
running�
The manual disconnect switch, located at the base of
the roadside lounge seat, can be used to turn off power
from the battery to the 12-volt distribution panel� Push
the knob in before manually rotating it to the ON/OFF
position�
The manual disconnect switch can be used to
completely disable the main disconnect switch by
over rotating the switch in the ON/OFF positions, until
a click is heard� The disable OFF feature is useful
for long term storage of the vehicle where the main
disconnect switch could be turned on and the batteries
accidentally drained� Likewise, the Disable ON feature
is useful while camping when the main disconnect
switch could be turned off, cutting power to appliances�
The holding tank heat pads, solar panel, and generator
are not connected to the 12-volt distribution panel and
are wired direct, through the thermal breakers� The
main disconnect will not disable these systems�
NOTE
As a safety precaution, the electric gas shut-off
solenoid closes automatically when 12-volt power
is disconnected, cutting gas to appliances. It will
reopen when power is restored.
Automatic Switch Over Box
The switch over box automatically switches the 120-
volt feed to the Energy Management System Module
from shoreline to generator and back as you choose
which way to power the touring coach� You simply
decide whether to plug into a 120-volt shoreline or
start the generator and the box will do the rest� If the
generator is accidentally started while plugged into
shoreline the box will sense the generator incoming
power, contact points inside the box will switch
cutting the shoreline connection, and establishing the
generator connection� This protects the system from a
possible overload from dual power sources�
Generator/City Power
A
B
C
a� To Energy Management System module main
breaker
b� From generator
c� From shoreline
1� When plugged into shoreline power, the current
path is from C to A�
2� When you start your generator, the points switch
and the power flow is from B to A. Stopping the
generator releases the points back to shoreline
feed�
3� If you’re plugged into shoreline and you start the
generator, the points still switch since the generator
has the priority, so the current flow is still B to A.
