
Do not hook up the power cord to any receptacle until you have verified
proper polarity and grounding. Polarity indicators can be purchased in
most electrical and hardware stores.

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.
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 personal injury or death.
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.
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.
3. Plug the power cord into the receptacle. Be sure all the power cord prongs
are properly plugged into the receptacle.
4. Return to your RV and turn "on" the load center main circuit breaker.
5. To help prevent power surges from damaging the connected loads, please
follow these instructions when hooking up to the external power source:
The shore line power cord should be unplugged when the RV is left
unattended. If something would happen to the electrical system, this may
help limit potential damage.
When you are ready to leave, reverse the power cord connection process. Use
care to prevent damaging the power cord electrical connection pins when
connecting or disconnecting the shore line power cord. Grasp the plug to remove
the power cord from the outlet; do not unplug it by pulling on the cord.
Maintenance
Inspect the power cord for cuts, cracks and worn insulation. Have the power cord
replaced immediately if these symptoms are noticed.
