120 Volt Power System
Power for the 120 volt AC electrical devices installed in your
motorhome is supplied by:
• The on-board generator
• Shore power
• The inverter
The standard inverter is not designed to power the entire 120
volt system and when used, care must be exercised so that
overloading the inverter is avoided. However, the inverter
supplied with the optional Re(li)able Battery Power System is
capable of powering all 120 volt appliances.
Shore Power
CONNECTING THE SHORE CORD TO A NON-
GROUNDED OR IMPROPERLY GROUNDED POWER
SOURCE CAN RESULT IN DANGEROUS AND POSSIBLY
FATAL ELECTRIC SHOCK.
Due to the potential danger in failing to heed this
warning, the motorhome manufacturer cannot be
responsible should damage, injury, or death result
from failure to connect the power cord to a properly
grounded power source.
DANGER DANGER
THIS CONNECTION IS FOR 110-125 VOLT AC, 60 HZ, 30
AMPERE SUPPLY. DO NOT EXCEED CIRCUIT RATING.
EXCEEDING THE CIRCUIT RATING MAY CAUSE A FIRE
AND RESULT IN DEATH OR SERIOUS INJURY.
Make sure the circuit breakers at the electrical power
source are in the OFF position before connecting or
disconnecting your shore line power cord.
WARNING WARNING
• The shore line power cord must be fully extended
when in use, and not left coiled in the electrical
compartment or on the ground.
• Do not use cheater plugs, adapters, or extension
cords to reconfigure incoming alternating current
(AC) power or break the continuity of the circuit
connected to the grounding pin.
• Do not connect the shore line power cord into an
outlet that is not grounded, or adapt the power cord
plug to connect it to a receptacle for which it is not
designed.
• Do not remove the grounding pin to connect to a
non-grounded receptacle. Removal of the ground
pin disables an important safety feature designed to
prevent shock and electrocution hazards.
• Do not connect the shore line power cord to an
extension cord. Use of an improper extension cord will
cause overheating of the cord as well as potentially
causing premature failure of the AC equipment.
WARNING WARNING
The campsite 120 volt power receptacle(s) should
always be tested for proper functionality prior to
connecting your motorhome’s shore line power cord
to it. Do not hook up the shore line power cord to any
receptacle until you have verified proper polarity and
grounding.
DO NOT plug the shore line power cord into a campsite
receptacle:
• That has reverse polarity
• With non-functioning ground circuits
• That shows outward signs of heat or other damage
Doing so may result in property damage or serious
injury. Damage or injury resulting from a connection to
a malfunctioning or improperly wired power source is
not covered by warranty.
It is the responsibility of the owner of the electrical
receptacle to ensure that the receptacle is properly
wired and grounded. Reverse polarity and/or improper
grounding of your motorhome can cause equipment
damage, personal injury or death.
WARNING WARNING
• It is strongly advisable to test the wiring of any
external power source BEFORE connecting your
motorhome. Along with a proper ground, the 120
volt AC source must have properly wired neutral and
hot terminals.
• Testing for correct power source wiring can be
easily accomplished with a portable polarity tester,
obtained from a RV parts supplier or dealer. Follow
the instructions provided by the manufacturer when
operating the tester.
• If a problem with the external power source is found,
CONTACT THE CAMPSITE MANAGER for repairs.
Do not attempt repairs to the site power source and
do not connect your motorhome to the site power
source until it is determined safe to do so.
