Electrical Supply; Shore Power - Regency ULTRA Owner's Manual

ELECTRICAL SYSTEM OPERATION

ELECTRICAL SUPPLY

Your motorhome is equipped with two electrical
systems that operate on separate voltages:
o an internal 12-Volt DC system (coach batteries)
o an external 120-Volt AC system (shore power)
The 12-Volt DC system draws power from either the
engine's battery and charging system while driving or
from the coach batteries when parked.
The 12-Volt DC system operates from the coach
batteries, from shore
inverter/charger or from the generator through the
inverter/charger.
The coach batteries charge automatically when the
unit is connected to shore power or when the engine
or generator is running.
The 120-Volt AC system operates either from the
optional 120-Volt AC generator installed in your
motorhome or from the outside shore power
connection.
WARNING
Do not connect the external power cord until you
have confirmed the campground has the proper
polarity and grounding.
Improper grounding or reverse polarity may
cause component failure, injury, or death.
The 12-Volt DC electrical supply is controlled by the
main power switch located in the coach doorway.
Press the switch in at the top to turn the main power
on, or press the switch in at the bottom to turn the
main power off.
