DC-DC Battery Converter

The DC-DC Battery Converter is located under the
driver's seat� It is designed as a power gateway that
only allows a maximum of 40 amps to pass between
the vehicles alternator and the house batteries�

Protecting the Charging System

The DC-DC Battery Converter monitors the house
battery system to determine if the batteries are being
charged� The charging can be accomplished through
the inverter/converter or the vehicles alternator�
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.

Inverter

The Inverter is a DC to AC inverter� The remote control
module is mounted in the overhead compartment,
behind the drivers seat�
The Inverter converts 12-VDC to 120-VAC current for
distribution to the inverter powered circuits and for the
microwave� To operate these outlets the inverter must
be ON, unless connected to generator or shoreline
power�
If power is not needed to these outlets, or for the
microwave, make sure the inverter is turned OFF
to conserve battery power� The inverter will have a
small power draw even when turned off but the power
consumption will be even greater if left on�
NOTE
Airstream calibrates all settings at the factory and
recommends adjustments not be made.

NOTE
Overloading the inverter will cause an automatic
shutoff to activate. Removing the load will allow
the inverter to reset.

Converter

The Airstream converter system enables you to use
the 12-volt lights and equipment whether operating on
self-contained battery power or hooked up to 120-volt
city power� The 12-volt lights give off the same light
as regular household bulbs, so that when operating
on self-contained battery power, everything works
normally, except the 120-volt inverter outlets and 120-
volt appliances�
CAUTION
When operating with city power, make very certain
that the service is 120 volt, not 240 volt.
The converter system is a transformer designed to
maintain constant output voltages regardless of the
variances that occur in city power systems� The design
eliminates the need for complex electronic sensing
systems to charge the batteries, minimizing the
possibility of failures and greatly increasing its overall
reliability�
In some older parks and other locations where three-
pronged outlets are not available, certain precautions
to ensure proper grounding and polarity must be taken�
These precautions are listed below:
1� Attach the three-pronged plug to a two-pronged
adapter� The third conductor line of this adapter
has a short wire lead that must be grounded�
2� For proper grounding, connect the short ground
lead to a grounded outlet box or to a cold water
pipe� When no water pipe is available, drive a
metal rod two feet into the ground and attach the
ground lug to it, thus providing the unit with proper
grounding�
NOTE
When the three-pronged plug can be used,
there will be no problems with proper polarity or
grounding with a properly-wired shoreline outlet.
