CLASS C MOTORHOME
Plugging the shoreline power cord into an incorrectly wired power source
could damage the motor home electrical system and result in severe or fatal
injury.
Occasionally the electrical service provided by a campground may experience low
or high voltage (i.e., surges or spikes). Any prolonged exposure will shorten the
life of the electrical system and appliances. Consult your dealer for
recommendations
Connecting the power cord
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.
Always test the 30 amp 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 30 amp 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 motor home 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 motor home 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.

When connecting appliances to the electrical system, remember that 120-volt
power usage is limited to a total of 30 amps. Be mindful of the fact that each
operating appliance collectively places an added load on your 120-volt electrical
system.
