INSTALLING THE BATTERY FUEL GAUGE
Follow the manufacturer’s instructions to install the
battery fuel gauge.
The shunt must be connected between the last
battery and the inverter negative post. You may
install the shunt at the battery or at the inverter. The
aluminum bar may be moved to accommodate either.
Make sure that you attach the shunt with the polarity
correct by following the labels marked “Load” and
“Battery.”
Attach the small red wires to the positive battery post.
If the cables need to be extended, use conductors of
the same size. Connections that are outside should
be at least butt-connected and covered in outside-
rated shrink tube. Waterproof plugs are also a good
method.
The battery fuel gauge display should be mounted in
an easily accessible place, probably the same area
in which you will mount the HVAC or inverter controls.
Consider rst the area at the head of the bed (driver’s
side of the truck). Usually the truck’s HVAC controls are
mounted here and provide a wire chase for your use.
The fuel gauge requires a hole size of a standard
round truck gauge. A hole saw of 2 1/8” gives the
correct mounting hole.

Battery-Powered Systems Installation Guidelines
INSTALLING THE INVERTER
Follow the manufacturer’s instructions. Here are some
other suggestions:
The inverter should be installed in the same box as
the batteries, so as to keep the cable lengths short,
reducing voltage drop to a minimum.
Mount the inverter directly to the metal of the box,
with no material or spacer in between.
Make sure to ground the chassis of the inverter to
the chassis of the truck. Note that 12-gauge wire is
acceptable for this requirement.
Install the Dometic 200 amp circuit breaker or a
properly-sized fuse in the positive cable between the
last battery and the inverter.
Note: If the inverter is to be installed anywhere
other than in the battery box, consult Dometic Truck
Engineering.
OPTIONAL: INSTALLING THE INVERTER/
CHARGER
The inverter/charger and controls will be installed in
the same manner as the inverter (Fig. 4). However,
the inverter/charger will be connected to the
shorepower connection (to be discussed later in this
manual).
