Section 6: Electrical System
Do not hook up the power cord to any receptacle until you have verified
proper polarity and grounding.
DO NOT
plug the shore power cord into a campsite receptacle(s):
That has reverse polarity
With non-functioning ground circuits
That shows outward signs of heat damage.
Doing so may result in property damage or serious injury. Plugging
the shoreline power cord into an incorrectly wired power source could
damage the recreation vehicle electrical system and result in severe or fatal
injury. Damage or injury resulting from connection to malfunctioning
or improperly wired power sources is not covered by your recreation
vehicle warranty.
DO NOT
Do not use any cheater plug, adapter or extension cord to reconfigure
incoming AC power or break the continuity of the circuit connected to
the grounding pin.
Do not connect the 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 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.
The power cord must be fully extended when in use and not left coiled
in the electrical compartment or on the ground. If the power cord is left
coiled, it may potentially create enough heat to melt its protective casing.
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 RV can cause property damage or serious
personal injury.

Connecting The Power Cord
Always test the external power source (i.e., the campsite power receptacle or electrical
box) with a ground monitor before connecting your power cord to it. If the ground monitor
indicates ‘reverse polarity’ or an ‘open ground’ DO NOT connect the power cord.
To help prevent power surges from damaging the connected loads, please follow these
instructions when hooking up to the external power source:
1.
Turn “off” the load center main 120-volt circuit breaker.
2. Carefully extend the entire length of the power cord (approximately 25’-35’) from the
electric cable hatch to the external power source.
