120V AC shore power is powerful enough
to kill you. Always use a grounded shore
power connection and never remove
the “third” ground prong from your
shore power cord. Both reverse polarity
or improper grounding in the 120V AC
supply outlet can cause serious injury or
death. Do not connect the shore power
cord if either or both are present.
WARNING
ELECTRICAL
ELECTRICAL SAFETY & INFORMATION
Two electrical systems are outfitted on your camper – the primary 12V
DC and 120V AC shore power. These electrical systems are engineered
to efficiently provide power to the various appliances and features in the
camper. All designs, components and wiring methods of the electrical
systems conform to federal and RVIA installation requirements at the time
of production.
Electrical Safety and Information:
• Aftermarket changes made to the electrical system can result
in electrical and fire hazards. Never add appliances, features or
other unapproved changes to the electrical system without the
assistance of a qualified technician.
• Electricity can pose a hazard if you do not understand how the
electrical system works. Only qualified electrical technicians should
service the electrical system and make changes to it in any way.
• Install a surge protector in the supplying 120V AC outlet before
plugging in your shore power cord to protect your camper’s
electrical system from damage caused by power surges.
• ALWAYS disconnect electrical power at the source when you work
with the electrical system.
• Remove rings, wristbands or other metal objects from your person
when working with the electrical system.
• Before you connect your shore power cord to an external supply,
test the outlet with an outlet-testing device that indicates whether
reverse polarity or an open ground is present in the outlet. If the
outlet- testing device indicates either of those conditions, have the
outlet repaired. Outlet testing devices are available from your
dealer or an RV/camping supply center.
• ALWAYS fully extend the power cord. Do not coil the cord up.
Excessive heat build-up can cause the wire coating to melt, become
exposed and lead to an electrical hazard.
120V AC SHORE POWER
When connected to an external 120V outlet or generator via the 120V
shore power cord, your camper will be supplied with power. The electrical
system will be grounded via shore power if there is no open ground in the
supplying outlet or generator. The negative terminal on your battery serves
as a ground to your electrical system when shore power is disconnected.
The 120V electrical system provides power for:
• Air Conditioner (If equipped)
• Microwave (If equipped)
• Refrigerator (plus LP and 12V)
• Alde
®
System (plus LP)
• Converter
• 120V Receptacles
