Battery Charging

Because runtime varies based on demand and
environmental factors, the best way to ensure enough
battery power remains is to monitor the battery voltage
charge display on the Multiplex home screen; for more
information, see Multiplex System on page 5-18�
The most significant loads on the battery are heating,
cooling, and microwave use� The more these systems
run, the more energy consumption�
If inverter use is extensive, the house batteries will
deplete much quicker� Even when not using 120
VAC power, the inverter will draw a small amount of
power if left on� When not in use, turn the inverter
off to conserve battery power� Consider reducing the
temperature on the thermostat when using the heater
and increasing the temperature on the thermostat
when using the air conditioner� If you plan on staying
longer without access to a charge, you will want to
conserve your battery power by using as few lights and
appliances as possible�

Charging via Shoreline Connection

Plug the Smartplug Cordset (shoreline power cord) into
an external shoreline power supply (city power)� Check
that the cordset LED indicator light is blue and plug the
other end into the coach's roadside SmartPlug inlet;
see Shoreline Power Inlet and Cordset on page 6-8�
The 30A automatic transfer switch with shore
power sensing capability provides total electrical
protection from faulty external power sources� It also
automatically determines the shore power connection
amperage, which means no manual setting is
necessary�

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.
As an RV owner, you may want to install a 30A 120
VAC outlet in your home so you have a shore power
hookup readily available� However, you must have the
proper outlet installed� Typical household 30A outlets
are wired 240 VAC for home appliances� RV outlets
are 30A 120 VAC� Ensure your electrician is aware of
the difference, or they may mistakenly wire the outlet to
240 VAC�
NOTICE
Do not connect to a 240 VAC outlet. Connecting
to a 240 VAC outlet may result in permanent
damage not covered by warranty.

Charging via Generator

All generator functions are controlled via touchscreen
input at the Multiplex panel� For additional information
on generator operation and charging using the
generator, see Generator on page 5-15�
NOTE
The system will only allow the generator to run
until the battery reaches a 95% charge to avoid
running the generator indefinitely.
