Battery Charging
State of Charge (SOC)
Because runtime varies based on demand and
environmental factors, the best way to ensure enough
battery power remains is to monitor the State-of-
Charge (SOC) on the Multiplex home screen or
electrical screen� SOC is displayed as percentages on
the battery icon; for more information, see Multiplex
System on page 5-20�
The two most significant loads on the battery are
heating and cooling� The more these systems run, the
more energy consumption�
If the inverter use is extensive, the house battery will
deplete much quicker� Even when not using 120 VAC
power, the inverter will draw a small amount of power
if left on� Turn the inverter off if you are not using
outlets or running air conditioning/heating 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
The first step is making sure the battery disconnect
switch is on� It must be on for the battery to charge�
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 6-7�
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; see Automatic Transfer Switch on page
5-17 �
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�
WARNING
Do not connect to a 240 VAC outlet. Connecting to
a 240 VAC outlet may result in permanent damage
not covered by warranty.
