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.
Makesurethatyouattachtheshuntwiththepolarity
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

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 first 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.

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.
Makesure togroundthe chassisof theinverter 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-sizedfuseinthepositivecablebetweenthe
last battery and the inverter.
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).
