Battery Disconnect Switches

The manual disconnect switch, located at the base of
the drivers side rear jumper seat behind the decorative
access door, is used to turn off power from the battery
to the 12-volt distribution panel� Push 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 till 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, rear lounge motor, solar
panel, and generator are not connected to the 12-volt
distribution panel and are wired direct in 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.

Battery Separator

The Battery Separator is located at the base of the
drivers side rear jumper seat, and is accessed by
opening the decorative door� It is designed as a
solenoid priority system to protect the chassis charging
system from excessive loading, while allowing house
batteries to be charged�

Protecting the Charging System

The Battery Separator monitors the battery system
to determine if the batteries are being charged� The
charging can be accomplished through the inverter/
charger or the engine charging system� When the
engine battery or house batteries are charging, the
Battery Separator will engage, joining the two battery
banks� If charging ceases and voltage decreases in
either bank, the Battery Separator will disconnect the
two banks from each other, protecting the banks from
being discharged simultaneously�
NOTE
In the event the engine battery is depleted, Sprinter
recommends using a trickle charge only when
charging the battery. When jumping the engine
battery, do not use a power boost. Read and
follow battery charging procedures in the Sprinter
Owner's manual.

Energy Management System (EMS)

The Energy Management System is located in the front
locker behind the drivers seat� A complete, detailed
EMS manual is included with your owner's packet�
The ENERGY MANAGEMENT SYSTEM is
a centralized power switching, fusing, and
distribution center. Power from the 120-volt power
source is fed into the box. The potential of lethal
electrical shock is present in this box. Inadvertent
shorts at this box could result in damage and/or
injury. All servicing of this box should be done by a
qualified Service Technician.
