Section 6: Electrical System
38
When you are ready to leave, reverse the power cord connection process. Use care to prevent
damaging the power cord electrical connection pins when connecting or disconnecting the
shore power cord. Grasp the plug to remove the power cord from the outlet; do not unplug
it by pulling on the cord.
Maintenance
Inspect the power cord for cuts, cracks and worn insulation. Have the power cord replaced
immediately if these symptoms are noticed.
Batteries
House Battery
Your motor home is equipped with a nominal 51.2V smart lithium iron phosphate battery.
This battery is also equipped with a nominal 12V output.
Unless a battery has been fully discharged, the house battery is normally charged in one of
three ways:

The chassis alternator charging system supplies power to the house battery when
the engine is running and the alternator regulator allows a charge (depending on
SOC of the battery, temperature, etc.).

When the power cord is plugged into 120-volt shore power, the converter/charger
functions as a battery charger and will automatically charge the house battery
when required.

Power from the solar panels also run through the converter/charger to function as
a battery charger/maintainer when required.
Dry Camping
House auxiliary and chassis batteries should be fully charged prior to dry camping. When
disconnected from 120-volt shore or generator power (i.e., while dry camping or tailgat-
ing) all electrically operated appliances and accessories must be used sparingly. The smart
lithium iron phosphate battery capacity is 210AH.
During this period these appliances and accessories are being powered by the house battery
directly, and/or indirectly through the inverter/charger. If excessive amounts of power are
drawn from the house battery, they will become deeply discharged. Permanent battery dam-
age will occur after repeated deep discharge cycles.
Battery Switches
The Lithium battery is equipped with a Self-Resetting Switch and Self-Locking Switch.
For long periods of storage
Prior to long periods of storage, it is recommended to turn “off” the Self-Locking Switch
and minimize the self-discharge rate when your motor home will not be connected to shore
 Do not store anything inside the battery compartment(s)
or near the
batteries that could touch the battery or battery cable terminals. Contact
with the battery or battery cable terminals could cause an electrical short
circuit, discharge the batteries, or start an electrical fire.

Remove metal jewelry and always wear eye protection when working
around batteries.
 Make sure the inverter/charger is turned “off” before disconnecting the
negative battery cable from the battery bank. Keep the batteries out of
the reach of children.
