50 amp Shore Power
ThE MoTor hoME IS DESIGNED To BE CoNNECTED To a 50 aMP SErVICE
WhICh ProVIDES a CoMBINED ToTaL oF 240 VoLTS. The 240 Volts comes
from two separate 120 Volt lines that are in the shore power cord. The motor
home should never be connected to any power source that will provide anything
more then 120 Volts on either line coming in. Failure to follow this will result in
serious damage to internal items that are plugged in.
A 50 amp shoreline power cord is provided to attach the motor home to a grounded power source. When
connecting or disconnecting from a grounded external power source, always turn off the shore power breaker
to the power supply outlet. This will prevent accidental shock and flashing of electrical contacts.
Note: These three shore power outlets are most commonly used throughout the
United States:
BATTERIES
The chassis and or auxiliary batteries of a motor home may be located behind the front hood of the motor home
or in an exterior compartment.
It is important to make sure that batteries are kept charged. Take time to turn off all lights or other 12 Volt
conveniences when not in use. Connect the motor home to a 120 volt power supply when possible, instead of
draining the batteries. The charge condition of the batteries can be checked with the monitor panel. To check,
press and hold monitor test switch while reading the charge level on the battery gauge. Charge levels indicated
are divided into sections from weak through fully charged.
Battery Safety
BaTTErIES CaN EXPLoDE! always wear splash proof safety glasses when
working near batteries. Do not smoke or expose any battery to electric sparks
or flame. Batteries, when charging or discharging, generate hydrogen. hydrogen
and air is a very explosive mixture.
Do NoT ShorT aCroSS ThE BaTTErY TErMINaLS. The spark could ignite the
gases. Do not wear metal jewelry or a watch when working on a battery.
Before doing aNY work on electrical system, disconnect battery cable and
the 120 volt power cord. Do not reconnect the cables until all work has been
completed. This will avoid the possibility of shorting or causing damage to
electrical components or shock to the servicing person.
Battery electrolyte is a corrosive, poisonous, sulfuric acid. avoid contact with
skin, eyes, clothing, or any painted surface.
Sulfuric acid in the batteries can cause severe injury or death. Sulfuric acid can
cause permanent damage to eyes, burn skin and eat holes in clothing. always
wear splash-proof safety goggles and gloves when working around the battery.
If battery electrolyte solution is splashed in the eyes, or on the skin, immediately
flush with clean water for 15 minutes. In case of eye contact, seek immediate
medical treatment. Never add acid to a battery once the battery has been placed
in service. Doing so may result in hazardous splattering of electrolyte solution.
